First of all, and especially with such a common name, it is necessary to give someone enough information to work with.A geographic. Location is essential to know where to look....... Where did he live in the US ? Ifo he served in the USarmy he should have service/pension records..... You may order them from the NA RA.Have you gotten his death certificate? The death certificates of his children often have parental info......have you looked for him in the 1870- 1880 Federal Census? These are often avenues of research.
