I took a quick look on Ancestry to see how many persons named Sam Kaplan/Caplan there are in Brooklyn in 1950, born about 1892 - and there are about 20 of them. You could check through all those, to see if any might be your great uncle. Looks like you may have to search for all the Samuel listing separately.

Given that you show the children of Sam and Ida to have been born just after 1914, I checked through the NYC marriage records on FamilySearch, using the SteveMorse.org search page for these records. I found the July 1914 marriage certificate of Sam Kaplan and Chaye Paskovet (used the FamilySearch certificate number, then searched through the new NYC digital images using that number:



Ida's original Yiddish name was Chaya, which often was Americanized to Ida. The 1950 census does seem to fit your Sam and Ida, except for the woman's name being Yetta. Perhaps the census taker misheard her name. Or perhaps Ida had died. You could check through the NYC 1949-1965 death index, which is on Ancestry (just google to get to it) to see if you can find Ida. You can also check to see if Sam had died during those years as well.

The marriage certificate is interesting in other ways. It gives Chaya's address as Ellis Island - do you know why she apparently was detained there? Did Sam and Ida/Chaya know each other back in Russia? The marriage took place at City Hall in Manhatten. And Chaya signed her name in Russian.

Good luck with your searching.
