(William) Hamilton McClatchy Jr was the son of (William) Hamilton McClatchey Sr and Catherina McCollum. I have not been able to trace Catherina's family -- any info on her and her family would be appreciated, especially if it comes with citations.
Hamilton Sr is the son of John McClatchey, known as the 'Pioneer' to distinguish him from all the descendants named after him. John was married four times. His second wife was Mary Hamilton, and they were married in Limerick Ireland. She died shortly after Hamilton was born. John remarried to Rebecca Ross, and the three of them immigrated to NC when Hamilton Sr was about 9 (accordingly to Ham's obituary). Rebecca died sometime after that, and John married a fourth time late in life to a woman named Sarah, last name unknown. John had only one child, Hamilton Sr.
Hamilton Sr's and Cathrina's children were: John II, Mary, Margaret, Jane, Rebecca, Charlotte, Hamilton Jr (John II was the oldest and either Hamilton or Charlotte was the youngest, not certain on the sister's birth order).
There are dozens of men named 'John McClatchy'and just as many named 'William McClatchy' (various spellings, the difference between McClatchy/McClatchey/McClatchie is a modern one). Therefore you will have to be more specific which John and William you are seeking.
My line is Hamilton Jr > Albert Alexander McClatchy Sr m 'Frank' Frances Cole > Albert Alexander McClatchy Jr m. Mary Josephine Iley> Ruby Iley McClatchy m. Clifford Ulice 'Doc' Bowen > Jimmie Lou 'Jimi' Bowen m. William Huey Kitch > to me. My parents and grandparents are all deceased.
Please email me; I will get back to you in more detail. Some years ago I compiled all that I knew into a 120 page manuscript entitled 'The Southern McClatcheys : The Descendants of John McClatchey in America.' It can be had for the cost of photocopying and postage, which is about $25 these days. I would appreciate copies of any articles that you can provide about anyone that is a descendant of John McClatchey, or related to them, such as the Alexanders.
Note that Mary and Hamilton Jr both married Alexanders, and a number of other McClatchey descendants also married Alexanders. There are a lot of interconnections between the two families!
