Hello, I have done some research on this family as I am looking for a John Hopkins born before 1820 in NY State. He is the father of my William Henry Hopkins born Feb. 13, 1838 in Springville, Erie County, NY and Died Sep. 10, 1911 Odebolt, Sac Co., Iowa. Possible siblings of William Henry Hopkins are: Cyrus, Richard, John, Hetta (Henrietta?) Sarah, Elizabeth.
What I have on Elias Hopkins b1726 CT: Married Miriam Webster and they had a daughter Freelove Hopkins b1757 CT. She married Isaac Flower in 1778 and they later went to MA. Their son Isaac Flower b1783 CT married Lydia Alma Wheeler and they ended up in Ohio.
Siblings of Elias Hopkins b1726 CT:
Consider Hopkins, son Rhoderick.
Lt. Asa Hopkins b@1720 m. Abigail Harris(1), Rhoda Collins(2).
I do not have John Hopkins as a brother of Elias so that is exciting new information for me. If you have any further Hopkins info please let me know. I have a lot more info on siblings' descendants if you're interested.
