Known facts:-
1911 census single age 20 tram guard.
Known 2nd marriage (widower) to Isabella Nicol Elliott 3.03.1935 London when he is believed to have been a hotel chef.
unknown 1stmarriage??
Both 1901/1911 census have him as James Downing. no Henry or H.
Free BMD has 5 possible marriages as James H Downing between 1912-1935 (2nd marriage) but 'Evans' Qtr Sept 1912 not the right one.
No Free BMD marriages of James Henry Downing.
Dozens of James Downing marriages for same period.
Probably really need a family connection?
Anyone out there?
