My wife's grandmother was Anne Wilson from Ballymoreen a relative of your branch. If we have it right our Anne Wilson's father was William Wilson a brother of Michael Wilson that married Catherine Heffernan. Making our Anne and your Jane Wilson (nee Fitzpatrick) 1st cousins.
We are working on that Michael and William's parents were Daniel Wilson and Hanna Gleeson.
Michael and Catherine lived in Graigue not far from Ballymoreen and all in the county Tipperary.
hope the info ticks some boxes for you.
