Hamiltons of Gortanigan

[Rosniak]

My 2xgreat grandparents were Thomas Norris and Margaret Hamilton who married 9 Feb 1846. I have come to a brickwall with both of them unfortunately.

I know that Margaret's father was John Hamiton and that she was living at Gortanigan (Cappagh) at time of marriage. I can find her father John on tithe applotments in 1827. Out of Margaret's 7 children only 2 had children who lived to adulthood. Of those only one (my great grandmother) had any descendants.

I am reasonably happy that I have located a brother for Margaret in Alexander Hamilton who married Jane Brown in Mountjoy Church in 1855. Alexander was also living at Gortanigan and had a father John. Alexander and Jane had at least one child (John in 1857) and after that I can find no trace of them which is frustrating.

So I'm looking for something on Alexander & Jane or some evidence of other siblings for Margaret or something to help me locate my correct Hamilton family.

Thanks for reading!
