There is a Henry Holt with with wife Emma, age 35, 1845, b. Michigan listed in the 1880 census in District 177, Cincinnati, Hamilton County, Ohio, but there is not a child listed. With the info of his age and birth location: 1850 Belchertown, Hamsphire County, Massachutsetts William Holt, 40, 1810, Vt Tirzah, 35, 1815, Ma Henry W., 14, 1836, Ma Maritta, 12, 1838, Ma Cynthia, 8,1842, Ma 1860 Erving, Franklin County, Massachutsetts William Holt, 50, 1810, Vt Tizah, 44,1816, Ma Deer park, Orange County, New York P.O. Middleton Thomas Holt, 27,1833, Eng Mary A., 27, 1833, Eng Mary E., 6, 1854, NY Harriet E., 3, 1857, NY Jane M., 4/12, NY Henry, 26, 1834, Ma Can not locate Henry in 1870 with a match that is close enough to consider In the 1900 census Henry states that his parents were born in England, but I could not find a Henry with parents born in England, while he was born in Massachutsetts in the year 1835. Thomas and Mary state they they immigrated over in 1861, with them listed on the 1860 census and the oldest child being born in 1854, it a possibility that Henry is a relative of Thomas's, but it is also a possibility that the William is Henry's father. Just some thoughts. Donna
