Hi, I did consider this. I wondered if Phoebe and William considered that their Grandfather Charles Hulse was their father figure in place of their actual missing father. It's also strange that there is no birth certificate for William (it was mandatory to register births in 1895) - that I can find - or marriage certificate for Hannah (I have her birth cert), although there is birth certificate for Phoebe in 1896 in Northop.
