This is a progress check on various DNA research questions since my previous update in July. With this update, I am moving to a new format for the research areas.
Paternal side
1 - Identifying the Irish parents of Bridget, my 3rd-great-grandmother. In July I tried some new approaches, isolating the DNA matches in common between my Dad's results and his first cousin MO on FamilyTreeDNA. I have also been looking at a couple of bubble groups from Ancestry's Shared matches of matches tool who have ancestors connecting back to County Longford, Ireland.
There's another possibly I had not considered until I started drafting this post. In 1854, John and Bridget O'Brien purchased a plot of land in La Salle, Illinois from Patrick Dooley. Looking quickly on Ancestry, Patrick was likely born in Roscommon, Ireland. I need to look closer to see if he was connected to Bridget through family.
2 - Determining the generation of connection for the Pennsylvania O'Briens. I watched a webinar on generation of connection by Diahan Southard of YourDNAGuide, who I have heard give a version of this talk a couple of times, and I am going to try again. I still think these people either descended from a brother of my 3rd-great-grandfather John O'Brien or are a first family of John's before he reappeared in La Salle, Illinois about 1850.
3 - Looking for potential matches descending from the Westall/Thornhill side of the tree to do a mtDNA test (New research idea)
4 - Looking for mtDNA test candidates descending from the McIntosh side of the tree
5 - Locating another Jones cousin for YDNA testing
6 - Trying new-to-me tools to isolate matches descending from Ireland on MyHeritage
Maternal side
1 - Identify possible siblings of my 3rd-great-grandfather Gabriel Vasquez
2 - Working with DNA matches connected to the Amado side of the tree
3 - Awaiting mtDNA results (and XDNA data) from a Campuzano cousin who is testing through FTDNA
4 - Identifying the connection with the mystery Guerrero-Leyva matches
