Surname Saturday: Caster

Mary Ellyn Brady Cooper (1927-1015) was an enthusiastic and prolific family researcher before computers.  I have acquired some of her papers and will be publishing them for the benefit of her extended family.
This is a letter she sent in search of Omer Caster.  Included was a picture of Omer from 12 June 1962.
I have a few additional pages of information, but some contain sensitive family opinions, so I hesitate to publish those here.  If you are related to the Casters please contact me and I can forward info to you.
