Thank you Shelley for the great info which I have printed off. I was able to access all the records you gave except for the rootschat link regarding the will dispute. It just took me to google books and when I typed in his name and after that his wife it said there were no results. I am not a subscriber to google books and there was no PDF I could download. Is there some way you can sent the article to me?
There is no doubt in my mind that the Frederick Augustus Hastings Seymour is the same man as Frederick George Barton. He used the name of Major Hastings-Seymour in his 1920 contact with The Eagle newspaper in Brooklyn NY so a year later he married Montie E. McIntosh. Its indeed strange that they married July 15,1921 and she set herself on fire and died Sept 29,1921 and that she was married as you say just before she made a will. She did apparently have some medical(perhaps mental) problems as the article you referred me to said she killed herself because of ill health and had been in a Raleigh hospital several days before her death. It also stated that she had been married once before and had secured her divorce before marrying Mr Seymour.
Also of interest is that his marriage record indicates an age of 57 (born 1864) when Frederick George Barton was actually born 1858. Also interesting in the article is the reference to his wife and daughter being killed when their boat capsized. Mr Barton and his wife Celestine Elizabeth Barth, nee Miller had a daughter Elaine Barton born in England in 1892. A passenger list gave Celestine and her 10 mth old daughter Elaine returning to New York after Barton had been arrested and put in prison in England. I have an article from The Eagle in Brooklyn that said Major Hastings-Seymour came looking for information about his daughter in 1920 but she (Elaine) was reported to have died in a canoeing accident in Virginia in 1915 (said nothing about his wife being killed also, and there are other accounts indicating that Celestine was still alive after 1920 running a laundry in New York). The use of his names Frederick and Hastings and Seymour as Frederick Augustus Hastings Seymour wrt to Montie E. McIntosh I feel is much more than a coincidence. I think its just another alias he was going by. I suspect he was after Montie's money like the other five women he duped.
