Would like info on families/descendants of George YOKE who resided in Shenango Twp, Crawford Co.,PA. His daughter Sarah or Sally married in 1818 to James Coleman, in or near Jamestown, Mercer Co,PA. Would like to find record of this marriage or know is the marriage records are still in existance for this time period. I was told there was a Jamestown flood and the records do not exist. Is this true? Thanks, Charlene
