When you do come back to this side of the family I think you will need to buy the Alfred Hopkin/Rachel Langley marriage certificate.
Rachel is likely to be the Rachel Langley, 16, living in Sculcoates in 1901 with her parents William and Mary; age and father on the certificate would confirm.
There isn't an Alfred Hopkin of the right age, but there is an Ernest, 17, born in Hull, living in Sculcoates. Again, Ernest appears to be illegitimate. The certificate may give a clue.
