In the catalog of Christie's (New York) auction number 7936, which took place on 10 & 11 June 1994, there are excellent painted birth & baptismal certificates of these two sons of Daniel Stetler & his wife Susannah (born a Stroub)in Penn's Township, Union County, Pennsylvania, as items number670 and 671. (I know nothing else about the family.)
I have scanned these certificates in case any of Amos and John's descendants might like a copy. Someone in the Stetler family ought to have them--they are too good to be missed by the family.
My email address may be found by clicking on my underlined name above. If you want a copy of these certificates, either by email or by postal mail, please email me directly because I may not see your request if it is posted on this board.
If it were a certificate of a member of the Pease family, I'd certainly want someone to do the same for me.
