Sorry I've taken so long to answer you all but I have been doing some re-checking.
Here's everything again including your bits with ?s where things are still not clear.
1867 - Isabella Wallace was born in Whithorn, Scotland on 30.05. to Agnes Wallace (she is registered as illegitimate but a paternity case was heard and won but she did not use her father's name of Rodgers).
1871 - On the census she is 3 years old and living with her grandmother Jessie Wallace in Whithorn (in 1871 her mother married and was with her new husband).
1881 - On the census she is noted as a 13 year old stepdaughter (scholar) of Stephen Rice and his wife.
1891 and after - no trace in Scotland.
1902 - on 7.12. marriage between Isabella G. Wallace and Harry J. Greene in Kings County - she should be c. 35, he c. 28, so dates recorded are incorrect.
The 'G' in her name is not on her birth certificate but she uses it from here on.
What I'd like to know if possible about this marriage is were they both single? What were their occupations at that time? Is this information recorded anywhere?
1910 - Census - living in rented accommodation: 4706 New Utrecht Ave., Brooklyn, Ward 30, Kings County, no children recorded.
Head of household: Harry J. Greene, occupation Bookkeeper Wholesale Glass.
Born in NY, parents born in NY.
Wife: Isabella G. Greene, born Scotland, parents born Scotland, immigration year 1896.
Their ages are given as 31 and 38, this is incorrect: he is c.36 and she c. 43. As everything else tallies the ages must have been manipulated somehow.
Mother of Harry, Mary Anne Greene, 71, widow, she and parents born in NY.
Does anyone know what the census comment 'M1 for 9 years' means?
1920 - living in their own property, 708 Lafayette Ave., Brooklyn, Kings County. Did they rent out - were others living there too?
Iabella's immigration year was unknown - strange - does this mean someone else filled in the form, do you think?
1918 - This is also the address given on the WW1 draft index card and gives Isabella as next of kin. It also gives us the dob of Harry - 04.12.1874. This makes him 44 in 1918 - is this not rather old to be called up for war service? I suppose it was something like the Home Guard rather than active fighting?
His occupation on the WW1 draft was given as a paint something salesman in NYCity - a rather posh address too. But in 1920 he was noted as salesman Merchandis. so again a bit unclear.
Harry's mother seems to have died in the meantime - or moved out.
1922 - Harry J. Greene died in Queens - although they lived in Brooklyn this is possible - a hospital? He certainly seems like the right one and the ages match.
1930 - Isabella is a widow and living at 37 (sorry 35 was her friend) Goodwin Place aged 60 (really 63). Occupation given as Carrier China Busin...?
Immigration year 1889 - this does not tally with the year given in 1910!
Did she rent out rooms - are others recorded at that address?
1941 - Isabella G. Greene died in Manhatten - again, like Harry it could have been a hospital or someone else's house for that matter.
the Harry who died in 1936 can't be my one - unless a son, which I doubt. The only child I found that MIGHT be theirs was a Harold who died aged 1 in 1907 in Kings. As they didn't marry all that young it looks as though they had no children. Only her step brothers and sisters are mentioned in her will.
The cemetery address you gave me John is the one I emailed several times but my plot number is 2877.
By the way, the house is still there and looks not too bad - probably worth a fortune nowadays!
Many, many thanks to all of you: adhadowey, Yvonne, shellyesq, John. I really appreciate all the time and effort you've given to my post, also for all the useful suggestions etc. which I will follow up. You have managed to clear away some of the unknown and set some of the records on Isabella straight - band leader indeed!! Will let you know if I get any further with this.
