Hey Sandra,
It's Fred again.
I found Sarah in the 1870 census.
1870
DeSoto pct,
Jackson Co., IL (roll 232, pg 68)
Alex Mostall, 39, blacksmith, PA
Kate Mostall, 28, PA
Sarah
Millhouse, 12, IL
(perhaps the families knew each other back in PA)
Alex & Kate Mostaller are also in the 1880 & 1900 censuses, but no Sarah.
There is a 02/05/09 posting on the
Jackson Co. message board site by someone that has some of the cemetery records...check it out.
