Barbara,
I have a book entitled Mt. Pleasant. It was published in 1939 and left to me by my dad. He was an Allred. Although the book does not have an index, I have run across the name Seely while looking through it.
Justus Wellington Seeley, for a number of years, served the community as surgeon and dentist. I'd be happy to check through it for you if you give me some names.
I am attending the Allred Family Reunion in Spring City next weekend and could bring the book if you are going to be there. Let me know.
The book was printed and bound by Stevens & Wallis, Inc. in Salt Lake City. It was sponsored by by the Mt. Pleasant Historical Association and compiled by Hilda Madsen Longsdorf.
