I checked out the Outen web page previously and felt that maybe Sallie was Sarah but I didn't want to jump to a conclusion. The 1812 matches my estimate of 1813 rather precisely.
Your additional passage makes me feel rather confident this is the one. I agree with the advanced age. This Sarah lived at least to age 58 and quite possibly a good deal longer, I have her in the 1870 census along with her husband Evans Scott.
I'll check a bit further, but with the small population of this farming area, the proximity of only 7 or 8 miles between the farms their respective farms in Sussex,Delaware, it seems almost positive this is the one.
I'll be accessing the web pages and adding quite a bit of family tree with all the Outen material it includes. Is there a way to just merge FTM files. I'm not extremely computer literate but it seems logical that it should be able to be done. Can you help me here?
