I am searching for any information for ancestors/descendents of Theresa H. Weddington.

Her Mother may be Beatrice. In a 1910 Census there are several people listed in same household in Eastland TX:

Ryle Weddington age 69
Beatrice Weddington age 43
Robert W. Weddington age 24
Thresa (mispelled?) Weddington age 10

There is also a Will R. Hamilton age 83 at same household.

I came into possession of a book that has Theresa's name in the front cover. It also says "Woodrow School of Expression" and "Dallas, Texas", along with her home address. She lists the date of signature as 1922.
