I do not know anything about the HANLEY family but Joanne DUNKUM who married Alexander MONTGOMERY was my 2nd great grand aunt. I do not think they had any children because she died before 3/14/1832 when Alexander married his 2nd wife, Frances MANN. Alexander and Frances had a number of children. They died at Dixon Springs, Smith Co, TN. If you think I can help, I will be glad to hear from you.
