A collection of Margaret Syle’s correspondence, arranged alphabetically by surname. As with series 1, there is also a file of letters written by Margaret herself, as well as a file of letters from Henry. While Margaret has a few correspondents in common with Henry (mostly Syle family members and Rev. Francis J. Clerc), most of her correspondence is from a different circle of friends and relatives.

Correspondence not by or to Henry and/or Margaret. In particular, this series includes correspondence from some groups that Henry was involved in, including the Gallaudet Centennial committee and the National Clerc Memorial Union. Also includes some correspondence from and to other members of the Syle family
