Hi again Laura, Dinah Emblen(m)who is Charles' mother was christened Dinah Boulter and born in 1823. She married John Emblen in Sept Qtr 1848 in the Poplar area of London. Unfortunately their surnames vary greatly over census returns eg.Emblem, Enblan etc but so far I've seen the 1871,81,91 and 1901 census returns for them. Sorry to be brief but hope it all helps you. Best Wishes.
