The reason their are two Georges, sons of George-223, is because you created a fictitious George.
George-223 had one son George Hubbard-612 b. 1650 died 1675 ish, unmarried.
The George who allegedly died 18 March 1683, is I believe an entire fiction. Someone got the death of George died 18 March 1685 and the death of George died Jan 1683 conflated and invented a new person who shows up as the son of both Georges.
I am going to disconnect your George and a duplicate currently attached to the George of Guilford, merge them together and put a big note on them.
Thank you for your question. It helped me realize where the other fiction George got his start.
