Hi Andy,
I have a distant relative called William Henry Wilcox. He was born in Orton on the Hill, Leicestershire in Q2 1885. He is on the 1891 census living with his grandmother, Eliza, in Orton and is also on the 1901 census living with his parents and sisters in Outwood, near Wakefield. I cannot find him on the 1911 census, although I don't have full access. A couple of the Wilcox men from Orton had moved to the Coalville/Whitwick area in the 1880s so if he came back to Leicestershire he may have gone there. At the time of your ancestor's burial, my William would have been 28. Do you think they are the same person?
