My info re Simon Yearick says he was born 27 June 1755 in Germany and died5 Feb 1831 in Mifflinburg, Union, Pennsylvania.
I also have a note that says he was a Revolutionary Soldier.Tradition says that Simon was a former German sailor. The Lewisburg Chronicle of June 4, 1904 lists Simon Yearick as a veteran of the War of 1812 buried at Mifflinburg.
However, I agree that age 57+ was pretty old for the War of 1812.I've never tried to confirm that he was in the Revolution but his age then would have been a lot more probable.
I have only his wife's first name, Barbara.
Send me your ancesator's name and I will see if I have her in my Yearick file.
Does your book om Union County burials give grave site locations?
