per Lloyd Wright, descendant, Thomas emigrated to America with Easu Price’s family”Family lore says they immigrated to the US when "baby William" was three years old, which would have been about 1883”

This is all from family records or (mostly) memories, so I don't have any
hard documentation for any of the above. Good chance some of the names are
misspelled or worse.
Just a few amplifying comments:
1) As you can probably infer from the above, William Thomas Price's first
wife (Daisy) died in childbirth, or complications from same, and the baby
died as well. Mother and baby (her only child, Adelbert) are buried in the
same grave in Taylor, PA.
2) George (my wife's father) does not remember ever meeting his Aunt Edith,
and remembers Edith's daughter Peggy living with her grandparents. Whether
this was just some temporary state, or whether Peggy was orphaned somehow,
isn't clear from this memory.
3) As I may have mentioned before, I am not at all confident that this is
complete even in regard to the children of Thomas and Elizabeth, let alone
the next generation. The only part that I am pretty confident of is the
children of William Thomas Price.
