I am hoping to find the marriage of Frederick's parents and the ancestors for his mum.
Info from birth cert:-
Frederick William COX
9th November 1893
North Town Maidenhead Berks
(Reg) Cookham
Father:- Frederick Cox (Coachman)
Mother:- Margaret formerly HOWE
i think this is what Les is trying to find out and the other posts were to help
i mean we dont want duplications do we
we are not sure that the Margaret previously found is the correct one, with nothing to verify it , no marraige for Fred and Margaret
of course thismeans that the Margaret found could well be Les margaret
i guess shes looking for some sort of proof.
HOWE family

1893 Margaret HOWE has paired up with Frederick COX for a birth. Maidenhead
1866 William COX marriage Letitia BAKER Lambeth
1871 in Ewell, Epsom.
1881 William Cox widower. in Abingdon.
Did the sisters become orphaned after Julia widowed?
Who was Charles Cox's father?.....
Tanja, Valda, CP, and more, have helped so much in finding this info. The Cox brothers from Essex seemed to spread far and wide after the decline of Cronford ?Park Estate near Stock Essex in the 1820/30.
i thought that objective was clear
