Thanks for the interest shown and replies received so far. It seems certain that EV and Harriet had at least two children viz Ethel Howard b 1895 and Doris Ellen b 1898. Freebmd shows Ethel Howard as "Bickerdite" which is why I missed it. However, my main question is why I can't find any reference to Ernest Victor Bickerdike anywhere (and I have searched for him as Ernest V, and surname Bickerd*).
Nor is there anything for Harriet Bickerdike, other than in Yorkshire where the family name clearly originates. However, the 1911 census shows Harriet (now Goddard) as born London and living in Hastings, with a daughter Doris Ellen of the right age, so I agree this must be ours. But then that creates more questions :
1) where were they (EV, Harriet and daughters) in 1901?
2) what happened to EV?
3) when did Harriet marry Goddard?
4) is it possible that EV changed his name to George Bickerdike Goddard, or is this too far into the realms of fantasy?
As I say, this is a distant branch and I am not able to pursue subsequent generations yet. But I would like to be able to quote some subsequent info on EV and Harriet beyond 1893 (or now, 1898).
But more immediately, after considering all the ramifications well into the early hours, most of all I would like some sleep!
