John N, William M, and Robert H Hawthorn were living in New York in 1840-1860 time frame. William (Meredith) Hawthorn m Emily Post, Robert H m Mary Post. Emily and Mary were sisters. William and John had sons/grandsons named John Nesbitt Hawthorn. John and William give Penn. as their birthplace, at least on some of the census records. Robert gives Maryland as his birthplace. I believe they are brothers, since they sometimes are living in the same household. There may be another brother named Hugh, who lived with the family of John N. Any information would be much appreciated.
