well i found an irish cousin. adopted. also, this guy-

[OnDoutside]

19. I see a tree on Ancestry where there's a Daniel Cahill and an Ellen Louise Hipwell.

It mentions children being born in Kinnitty. If the data on that tree is correct (and I think he was born in Offaly not Cork as they suggest), they certainly led an interesting life ! That may be down to (if the 1861 census record is correct) Daniel being in the military, which may also account for him getting married in later life ? That census record says Eleanor was born in Stockport (near Manchester).

I believe this is Daniel's Military info

Name: Sergeant Daniel Cahill
Enlistment Age: 20
Discharge Age: 41

Note : Queen's County is the old name for Offaly.

On that one, it's saying that he was born 19 Jan 1818, in Tracton, Cork, Ireland (only about 15 miles from me). On this tree, they're said to have been living in Toronto in 1891 with 3 sons William, Robert and David.
