For the Boyce/Bice/Buys family there is such a range of dates and places I am wondering where the information originally came from. For Samuel Boyce, b 1783, I have found Springhill Twp., Fayette Co. Pa. and also Amwell, NY.
For his marriage Harrison County West Virginia and Greene Co. Pa - he was married twice from what I can find.
His death on 13Apr1841 is the only event that all seem to agree on - Colfax, Marion Co., West Virginia.
His wife Mary Stines birth is placed in Fayette Co, Pa or Germany.
It gets worse as you go to parents, grandparents.
