The Lancashire BMD Org. has the marriage of William and Catherine at St Timothy Everton Liverpool in 1875.

The marriage certificate £7 from this site may show family.

There was a William Poole, fish dealer, age 48 also living in the parish of Onchan in 1901, since he and Catherine appear to be buried in Braddan could the William in West Derby be someone else ?
