Lisa, Naturalization Record - of course - "Intention", the clue. Thank you for the link to the NY site. Had found them but hadn't yet gone any further. Have only been poking about since Nov of 2005 which is when I found out Russ had died backin 2002.
Suanj and Trish, Mongello is the surname Russ gives for his mother on his SSN app., his obituary, his death certificate. Assuming you folks have turned up his birth family - and I certainly think that IS the correct family -
then I'm willing to go with D'Ambrosio. But I will get documents
Russ was a very well liked, interesting fellow who for some reason continuously changed or embellished many, many facts of both his personal and military life - giving an incorrect name fits right in. Why, we don't know - - it seems to have been an irrepressible personality trait that invaded all aspects of his WHOLE life. Could have been that my mother just couldn't put up with that kind of thing and so she divorced him after about four years of marriage. And if you re-read (the selected) few quotes from her and Grandma that I have included in my posts and compare the information, BIG changes. You wouldn't believe the military embellishments and outright fabrications; all disproven by documentation.
Trish's suggestion re first wife's name vs second wife's name has been tossed about before but frankly, nothing seems to point to multiple marriages. Now, casual coupling, that might be a different story

but less and less do I believe that to be the case in this history.
Ah yes, a "jackpot" of information is an understatement. The whole story is practically uncovered in a few postings - unbelievable the amount of time you folks have so graciously saved me.
Widspirit, I too located a Katherine (my first name) Agneta in Cambridge, Mass. but, again, that is a research area I have yet to get back to. However, I do know that Cambridge is the town that my folks often visited and so feel that she is the correct Katherine for whom I am named.
FYI my mother was born in NYC but her folks moved to North Stonington, CT, in the early 1920's. So the trip to Cambridge was logically one to make whenever my folks visited Rhode Island from our home in NYC.
Very, VERY exciting stuff! My hat is off to all of you.
