A bit more detail:
Frank Thomas BRAHAM bap 19 May 1889 at St Paul, Islington. Parents - Thomas (entertainer) and Elizabeth, of 51 Richmond Rd.
Jessie Mabel BRAHAM baptised 5 July 1891 at St Thomas, Islington. Parents - Thomas (french polisher) and Elizabeth, of 178 Drayton Park.
There is a Thomas BRAHAM, 20, bach, french polisher married Lucy FLYNN, 19, spin, on 24 May 1874 at St Jude, Bethnal Green. (His father - James BRAHAM, picture framer).
Probable 1871 then at Bethnal Green:
James BRAHAM 43 Spitalfields (gilder)
Morgan 38 Mile End
James 20
Thomas 15 Spitalfields (french polisher)
George 13
Ann 10
William 1 Bethnal Green
RG10/477/63 pg 19
I can't see a suitable death for Lucy BRAHAM (nee FLYNN). This could be a reason why there is no marriage for Thomas and Elizabeth LEACOCK.
