There are lots of Simeons in my father's paternal side, I had an uncle, grandfather and gt grandfather with the name. My gt gt grandfather's brother was also Simeon. My gt gt grandfather had 7 siblings so lots of children born and several more Simeons going through generations to my father's generation. Two Simeons went to WW1, my grandfather being the one that came home.
I have found my 3rd gt grandmother had a brother Simeon born 1803 but he didn't make 1841 census or any other that I can find. Looks like the Simeon name comes from my 3rd gt grandmother's family. All her male siblings have biblical names. Simeon (New Testament) met Joseph and Mary when Jesus was taken to the temple when he was 40 days old. Simeon (Old Testament) the son of Jacob and Leah and leader of the Simeon Tribe one of the 12 tribes of Israel. Different Simeons crop up occasionally in both testaments.
Perhaps I had very religious 4th gt grandparents or perhaps if I get back past them I may find others in the family.
My husband's family used Tennant as a middle name quite often, my father in law's eldest brother bore the middle name Tennant - he died young. He would have been my husband's uncle. I had to go back to a lady born in 1781 (OHs 3rd gt grandmother) to find a Tennant marrying into the family.
