Thanks for the information regarding Samuel Kirby Lough. There was a Mary Bancroft who married Alonso or Aloynso Bangs in Hawkesbury. I haven't been able to establish a definite connection between Mary and my gg grandmother Elizabeth Bancroft as of yet. However, I think they may have been sisters or cousins and they would have known Elizabeth and Chauncey Bangs as relations through the Bangs family at that time. I found a Baptismal record on the internet that shows that Elizabeth Kirby Lough and Chauncey Bangs had Elizabeth Jane b. 29 Jul 1850 and William Chauncey b. 19 Jul 1852 in Ottawa. Also, I found that a Chauncey Bangsplaced 5th in the pairs event of the 1933 Montreal World Figure Skating Championships.
Anyway, I'm glad you found the website and I hope it will be of some help to you. I will be using this service again soon as I found it really helpful for establishing relationships and for gaining clues to direct my searches. Let me know how you do, if you decide to use it as well.
