Hi Diane
The reason I mentioned talking to the tree owner is if they know more than is published on the tree.
Like, for example as BumbleB says, the death certificate.
As an aside, I found this on HALS . . . . .
Peter Wallace, 31 Dec 1896, Little Munden, Accused Theft, Hertford Petty Sessions, Summary conviction
If you widen the HALS search then you get a small number of "Wallace" misdemeanours
