I would be greatful of a any hints or tip of where to go next as I am stuck fast.

I have been usingirish geneaoligy,LDS, fermanagh gold, archives.ie,genforum, and many many more, none of these are payment for use sites as I am unemployed.

I also have Fleming Vance buried with

I dont know if they were related by marriage to Fleming but Fleming is my ancestor. Fleming had a son Joseph who worked in service in Kilruddery in Bray as a butler. Thank you.
