I am trying to find James Walker's parents and/or siblings. James was born ca 1783 in Albany, NY, married to Isabella McMartin, went to Marion county, Ohio, sometime between 1817 and 1819 (he had children born in NY and in Ohio). He had numerous children, among them Catherine E. Walker who married John Hammond in Hastings, Ohio. She died in Pawnee City, Nebraska and is buried there. Her son, Marshall David Hammond, married Mary Elizabeth Stewart in either Morrow or Richland county in Ohio. That couple then moved to Kansas and then to Nebraska.
Any clues or information would be very much appreciated.
