You're welcome.
In the 1930 census, Harry is listed as born in New York, and his age at first marriage was consistent with his marriage to Christina.
He was also listed as born in New York in the 1940 census, but he has France as a birthplace in the 1950 census.
Harry's ages on the census also seems to be significantly younger than the California death index and Social Security death index mentioned above.
Also, his WWII draft registration card says he was born 8 Aug, 1892 in New Cross, England.
https://www.familysearch.org/ark:/61903/1:1:XR1P-Y53?lang=enSounds like Harry wasn't very forthcoming about his past and/or he was confused?
I didn't find any reference to Kathleen's death, but it looks like son Charles married & died in Canada, so maybe she went back there with him?
