I still think James Davies in 1891 and 1901, living in Wales with Eunice, is Reuben STRANGE. Why would he live with her and her kids (who are all registered as variants of STRANGE)?
Also James STRANGE in Newhaven, 1881 is 52, b circa 1829.
The James STRANGE she marries in 1882 is a widower.
James DAVIES in Wales in 1871 is 39, born circa 1832
The above may be the same person
James DAVIES living with Eunice in 1891 is 36, b circa 1855
James DAVIES living with Eunice in 1901 is 45, b circa 1856
Reuben STRANGE d 1926 aged 70, b circa 1856
The birth certs of their kids all give Reuben STRANGE, also her death cert (which gives wife of Reuben STRANGE
I think the last 4 statements refer to the same person.
