Descendants of John Scahill and Margaret Reilly

Hello,

I am looking for information for my information on my gr-grandmother, Bridget Scahill b. 1876

I believe her parents were John Scahill b. 1841(son of John Scahill and Margaret Reilly), and Honor Needham b. 1843

I have the 1891 census for Paisley Scotland, Parents are listed as John Scahill, wife Sarah

Children are Mary, Peter, Bridget, and Margaret.

I don't know why "Honor" would be listed as "Sarah", as all the other information seems correct.  

My gr-grandmother is listed on the 1901 census as living in the same house, but married to my gr-grandfaher, Stephen Cain, who was also born in Westport, Mayo. I am certain that my grandfather was born in the same house.

So, I am just trying to find a source for Honor Needham as the parents of Mary, Peter, Bridget, and Margaret. Also of the marriage of Honor Needham to John Scahill.

The Scahills have proved difficult for my amateur skills, the whole extended family seems to contain Bridgets, Johns, and Austins!  Thank you for any information,  Ellen Keane Ganssle
