Robert Leach is known only from his marriage to Jane Lockhart on 4 April 1853, the ceremony conducted by Rev. Villeroy Reed at First Presbyterian Church, Lansingburgh, New York (near Troy). The record does not show names of Robert's parents or his age. Assuming that he was near his wife's age or slightly older, that places his birth about 1825.
There is a naturalization record at New York, also dated 1852, for a Robert Leach, born in "Great Britain Ireland". Could that be the same person? Not enough information.
There is a military record showing that "Robert W. Leach" from New York was a private in Company E, 62nd Regiment, New York Infantry, during the Civil War. Did the initial W. stand for anything? Where was he from? Did he have a wife? All unknown... records are poor.
Jane's mother and siblings are known to have moved to Chicago about 1860. Did this couple move to the same place? Various people named Robert Leach / Leech / Leitch lived at or near Chicago after that date. But positive identification is difficult; again, records are uninformative.
