My MAHAN family came from Mercer Co. PA as best we can tell the first one was William MAHAN his son James was in Mercer Co 1810 and 1811. As James and wife Jane's first two sons were born there in those years. They were in Ohio in 1816 & 1817 and Ind by 1822,23, 26 and MO by 1830. If anyone could find marriages of William also James and Jane would love to know who wives maiden names were. I joined Mercer Co Genalogy society at one time and was sent some early history of mercer Co. and William Mahan was mentioned. They may have been in surrounding counties prior to 1810. But have one sons obit and it states he was born in Mercer Co. Pa Aug 10, 1811. any help appreciated.
