I know that his sister Cissie (or Cecile) celebrated her birthday on July 4th. However her British birth certificate is easy to obtain, and she was really born on August 16th. The Newmark family settled in an Irish area of St. Louis on their arrival in America, and I wonder if some of the children adopted local celebrations near their birthday as their own.
In a way, I owe my obsession with genealogy to my great grandfather's fib. It made for a fun story to tell my friends on the holiday, and one of those friends was also obsessed with genealogy, so he conducted a search, and sent me a link to the 1920 HeritageQuest census for my great grandfather. Once I realized what was available online, there was no turning back.
