Thank you for your enquiry about Anna Mae Druce (born abt. 1891).
I have found a John Druce (b.1860 in Witney, Oxon.) and Emma ? (b.1860 in Oubridge, Oxon.) and daughter Sarah E.Druce (b.1880 in Witney, Oxon.) in the UK 1881 Census Records. John's occupation at the time of the Census was that of a Grocer's Porter. However, at the moment I cannot trace any connection between the Witney Druces and those from Frome, Somerset.
