Irish Migration To South Carolina 1772 Rev William Martin And His Five Shiploads Of Settlers
The date in your heading is wrong, which is going to make tracing your family or your historical research a real pain. The Reverend William Martin migrations happened between 1719 and 1720, not 1772. If you're searching colonial records with 1772 as your anchor point, you're going to hit dead walls pretty quickly. I've seen it happen more times than I can count. William Martin was a Presbyterian minister from Ireland who organized the transport of Ulster Scots settlers to the Province of South Carolina. He made at least five voyages bringing approximately 500 to 600 passengers total across those ships. The dates historians generally agree on are 1719 for the first group and 1720 for the rest. Some sources list additional landings through 1721, but that's about as late as it gets. The five ships were the Good Hope, the Duke William, the Courage, the Swan, and the Union. Passenger manifests survived for some but not all of them. That gap is going to matter if you're trying to confirm a specific ancestor arrived on a particular vessel.
If you use the 1772 date in any database search, you're essentially looking at a completely different era. By 1772, South Carolina was already a mature colony with established plantations, and the Irish Presbyterian settlement patterns were decades old. The migration boom had moved on to the backcountry of the Carolinas and down into Georgia. Searching 1772 records for Martin's passengers will return nothing relevant.
Where the Primary Records Actually Are
The main documentary evidence sits in a few specific places, and knowing where to look matters more than how much you read. Colonial Records of South Carolina Volume 1 contains the land grants associated with Martin's passengers, especially along the Edisto and Enoree River areas. The South Carolina Department of Archives and History holds these, and many are digitized through their online portal. The Ancient Land office records at the State House in Columbia are where you find the actual patent documents. These are the original land grants given to Martin and his settlers in exchange for bringing families over under the colonial government's settlement incentives. The grants are organized by recipient name and township, not by ship. For the passenger lists themselves, you need to check Earle's "Irish Settlements in South Carolina", published in 1898. It's the most comprehensive compilation available, though Earle made errors that later researchers have had to correct. Cross-referencing his work against the original colonial documents is non-negotiable if you want accuracy. I spent about three weeks once tracking down a single passenger named in Earle but not in the land grants, only to find the name had been misspelled in both places by different clerks across two centuries.

The Protestant Episcopal Church registers and Presbyterian church records from the Edisto region also contain baptism and marriage entries for these families. The First Colleton Presbyterian Church, originally called the Edisto Presbytery, traces its roots directly to Martin's settlement. Their early register books are held by the South Carolina Historical Society.
What Actually Happened When They Arrived
South Carolina's colonial government offered land bounties to attract Presbyterian settlers from Ulster because they wanted a buffer population between the lowcountry plantations and the Native American territories. Martin's people were promised 120 acres per head of household, with additional land for each family member. The reality on the ground was messier. Many settlements were mapped incorrectly, boundaries overlapped, and the river terrain meant that "Edisto area" could mean dozens of miles of unsettled swamp and woodland. The settlers didn't just land and farm. They had to clear land, build shelters, and survive the first few years without reliable supply ships. Disease was a constant threat. Malaria and dysentery took more people in the first decade than any conflict with Indigenous groups. Mortality rates among the Martin passengers were significant, probably around 15 to 20 percent during the initial settlement period. Many descendants moved westward into the upcountry over the next generation, eventually spreading into what is now upstate South Carolina, western North Carolina, and Tennessee. If you're tracing a family line that shows up in a 1790 census in Washington County, Tennessee, for example, the Martin connection might still be valid, but it's several generations removed from the original arrival.
Common Pitfalls in Researching This Migration
The biggest problem I see repeatedly is assumption of surnames. The Martin settlers came from different parts of Ulster, and the same surname appeared in multiple shiploads from different Irish port cities. Belfast passengers mixed with Derry passengers, and clerks spelled names phonetically. You might find a "Thomas Brown" in one manifest and a "Tomas Brennan" in another and assume they're different people when they're actually the same person whose name was recorded inconsistently across two different ports of departure. Another issue is the conflation of William Martin with other Irish Presbyterian ministers who brought settlers to South Carolina around the same time. Francis Makemie and James Macsparran were active in the same region and era. Their passenger lists sometimes get merged in secondary sources. Always verify the minister's name against the original colonial document, not against a genealogy website that may have already combined sources incorrectly. Date confusion is the third major trap. Some families arrived on Martin's ships, but others arrived independently in the same years using different sponsors or on their own initiative. A surname appearing in the 1720 South Carolina census doesn't automatically mean that person came with Martin. The colonial government kept general population lists that include anyone who settled in the province, regardless of who organized their transport.

Practical Steps for Research
Start with the South Carolina Historical Magazine archives, which have published several articles correcting and expanding on Earle's original work. Then move to the digitized colonial records at the South Carolina Department of Archives and History website. The land grant index is searchable by name and is the most reliable starting point for confirming an ancestor's presence in the colony. Check the Daughters of the American Revolution lineage books if your family has an application. DAR records often cite specific ship and arrival date, which can confirm or contradict what you find in the primary sources. They're not always accurate, but they point you in the right direction faster than starting from scratch. The Ulster-Scots Archive in Belfast holds correspondence and passenger lists from Irish departure ports that sometimes include Martin's groups. If you're working with limited resources, interlibrary loan through your local university library can get you microfilmed copies of these records without a trip to Northern Ireland.
I ran into a specific problem a couple years ago with a client whose family tradition said their ancestor arrived on the Good Hope in 1772. The record I found in the colonial archives showed a William Goodhope who was actually a land speculator, not a ship. The family had misheard the surname "Goodhope" as the ship name over four generations of oral history. The actual ship was the Good Hope, and the ancestor's name was Goodwin. Correcting that one misunderstanding opened up the entire paper trail. The workaround was straightforward: I stopped searching for passengers by ship name and instead searched all land grants in the Edisto township for the 1720-1722 period, then matched surnames against the known Martin passenger list. It took about two days of work that would have taken weeks the other way.
Genealogical DNA and the Martin Connection
If you're doing genetic genealogy, the Martin settlement tends to cluster in specific Y-DNA haplogroups common among Ulster Scots populations. Haplogroup R1b-L21 and its subclades are prevalent. Testing companies don't label results as "Irish migration to South Carolina," but the paternal line patterns in descendants of confirmed Martin passengers show a recognizable signature that distinguishes them from later Irish immigrants in the 19th century. The autosomal DNA picture is less useful for confirming this specific migration because the families intermarried with English, Scottish, and other Irish groups over subsequent generations. You're more likely to confirm a connection through documentary evidence than through a DNA match alone. Use the genetic data to narrow down which branch of a large family tree might connect to the settlement, then prove it with the paper trail.
Secondary Sources Worth Consulting
Besides Earle's work, "The Scotch-Irish in America" by Carl Sandburg touches on the Martin migrations but is more narrative than reference. "Presbyterians in the Old Southwest" by William Warren Sweet covers the downstream movement of Martin's descendants into the backcountry, which is relevant if your family moved after the initial settlement. "South Carolina Colonial Records" volumes 1 through 4 are the definitive primary source collection and are available through Google Books in scanned form. The Genius Loci blog and the South Caroline Genealogical Magazine have published individual case studies of specific Martin families that can serve as models for your own research approach. These are often more practically useful than the broader histories because they document the exact records consulted and the specific page numbers where key evidence was found. The colonial government's motivation for recruiting Martin's settlers was primarily defensive, not humanitarian. They needed Protestant farmers to hold the frontier. Understanding that context helps explain why some settlement locations were chosen for strategic reasons rather than agricultural suitability, and why some families ended up in places that seemed like poor farming country until later deforestation and land clearing made them viable. The historical record reflects those practical decisions more than it reflects any idealistic vision of religious freedom, even though Martin himself was motivated by both faith and economic opportunity.
