I have recently got information that our great grandfather was in fact William Charles Drieberg ! However we also have a marriage certificate that proves in 1854 he married Jane Robertson in Liverpool under the name William Thomas Driberg. Then he married Selina Wells 1861.Used his proper name then.When he came to NZ he married Eliza Davies in 1867.Used William Thomas again. Do you please have any other information to help us fill in gaps ? Our email address;email@example.com Many thanks and hope to hear from you soon. Lyn.
