I am looking to fill-in the descendants of Thomas Quilliam born 1822 twin brother of my ancestor William Quilliam both sons of John Quilliam of Ballakerkey.
I know he had at least 8 children by his wife Mary (4 boys and 4 girls) but I do not know anyting as to their descendants.

I do know, however, that the well known author George Leslie Quilliam was of this line but I do not know how to connect him.

I am also looking for any information on the descendants of William Quilliam and his wife Catherine "Kate" Chrsitian Crellin.

Any help would be greatly appreciated.

Many thanks,

James Quilliam
