FamilySearch Wiki on Roscommon

FamilySearch wiki for Roscommon, Ireland.

As I dive further into the records on the Gannon and Hanley families in Roscommon and Longford, Ireland, it is a good reminder to check what sources are available using the helpful FamilySearch wiki. My particular connections point to the border of Roscommon and Longford, at the historic crossing of Termonbarry. While I've looked at some of these records in the past, it is always helpful to revisit these sources to see if there are new records that might have been added or overlooked.

Research Progress September 2026

With the calendar change to a new month it is time for another recap on my research progress. The main focus of August was the DNA Skills course and determining the family of my Irish immigrant 3rd-great-grandmother Bridget. Toward the end of August I seemed to have enough DNA signs to make the case for Daniel Gannon and Maria Hanley as the parents of Bridget.

There's a bit more work to do, and I am continuing to build out a genetic map linking a 44 cM match descending from a brother of Daniel Gannon, and a 23 cM match descending from a brother of Maria Hanley. The Gannons may have had a sibling who left Ireland for Australia, as there's a cluster of Australian matches also in common with HD, the 44 cM match, and his niece, a 26 cM match.

The other research questions I listed in my August post carry over to this month. I may switch over to the maternal side of the tree once I've had my 1:1 meeting with an expert coach as part of the DNA Skills course and confirm if I'm on the right track with my hypothesis for Daniel and Maria.

When I was in Dublin back in October 2025, I had a one-hour consultation with an expert at the Irish Family History Centre. Among the many suggestions she provided, one was to look at the resources on JohnGrenham.com. There's a tool where you can plug in two family names and see how they overlap in the records. At the time, we were looking at Dooner and Hanley, along with Farrell and Casey. With my latest discovery, I plugged in Gannon and Hanley, and the overlap is pretty clear.
