It looks to be the right people on the census and the marriage.

Can anyone tell me the other members in the household (if any) on the 1891 and 1901 censuses.

Wondered why he was not with his wife on the 1891 census. They are both in the same town so the reason would not be working away!

Also has anyone any info on Mary Coole at Sulby Bridge? Seems likely the father got remarried to her.

Came across this on MNB may be coincidence?
