Hi Janice,
I have just come across your posting, there might be a connection, just dont know where yet,

Eliza Barton nee Key/Kay was my 3x grandmother, b/ 24 may1835.[ i have info on her children,][1881 census]
I gained a copy of her baptisum record,and it had her father as Patrick Kay, and mother as Catherine Turbitt,[i have info on other children]
yet on the 41,51 census, at the family search center in Peel, Catherine is wed to a Robert Kay,[no record of him on the 61 census]
Eliza is also recorded as living with Elizabeth Turbitt[her aunt?]and a Patrick Kay.

Not sure if this info is of any use to you, at the moment, but i,m having a hard time, trying to sort it out,

Ill keep checking, and ill get back to you,as soon as poss,
Regards yvonne.
