Hi there

The sister of my great-grandfather, Nelly Henrietta L Hilsden (b.1878 Bucks) travelled to New York, and married a man named John Tudor.
I have her on a passenger list (Canadian I think...) in 1920, then in the US fed Census in 1920 living in Jamaica, Queens New York. I believe she actually got married in 1921, but have no marriage record for her.
John Tudor apparently died around 1960 (have no record of that) and Nelly died in Canada, I have no date for that either!
Nellie's sister Selina lived in Canada, as did several cousins and in his later life, her father as well.
Family legend suggests, that on one trip back to the UK, Nelly was afraid for her and her husbands life. Although I noted the residence and dates of the US census, I have lost the copy doc I had from Ancestry...is anyone cen help me with that.
But can anyone help point me in directions that would discover more about this couple? Sadly they had no children.
Thanks.
