Hello Donna,
I have not been able to find a Robert Cain born in 1829/1830 that fits.
unless we have missed a generation in between Robert 1804 and Robert 1829/1830 ?
do you have the Burials for - Robert Cain and Jane Kissack ? - to check for Wills.
we need to sight a copy of the Marriage of - Robert Cain and Margaret Crowe 12 Nov 1853 Braddan
to see their parents names ?
