Looking for more on Margaret, I found a grave for someone with that name in the same cemetery where Sam & Anna are buried...in fact, Margaret's plot is in the same block and section as Sam & Anna, and the burial society (1st Hungarian Independent Lodge) is the same for all three. 2022 update: Cemetery is Riverside in Saddle Brook, New Jersey. Sam's Find a Grave memorial is here.
Now for the mystery: The next of kin listed on Margaret's cemetery info is "William Schwartz, son." Although I don't know whether this is the correct Margaret (I've guessed wrong before!), nobody has ever heard of Margaret and Sam having a son. Is William Schwartz a distant relative? Does he still have any of Sam Schwartz's family heirlooms?
Mystery solved! My cousin Bonnie told me she remembers that Margaret had a child from her first marriage, so William might have been my great-uncle Sam's stepson. However, it turns out that William is NOT the correct guy. Margaret's son was named Simon, as I learned when I found him with his mother and stepdad in the 1950 US Census. My 2024 conclusion is: Margaret Schwartz buried in Riverside unlikely to be the person in my family tree.
