I don't think the following is a coincidence:
Kelita Suit, s/o Benjamin Suit & Mildred also had a son with the same name JBT as did Norris Suite, s/o Samuel Suit who was s/o James who was s/o Benjamin.
I still think that Benjamin Sweeney Suit was s/o Samuel Suit and Elsie Jones as they did have another son other than Norris on 1840 census. There is no 1830 for St. Mary's Co. that I am aware of.
I also say this because "Elizabeth Jones" is living with him on the 1860 census. I am sure she was Elsie Jones Suit, widow of Samuel Suit/Suite s/o James Suit who d. 1813 in St. Mary's Co. MD. The age is a match.
Also, according to the will of Dent Suite who d. 1792 and clearly only named some of his children named his 3 oldest sons John, Thoomas, Benjamin.
