I found your query on the web for Dolly Peek as your grandmother.
My husband, Brian McDaniel’s, g-grandmother’s name was Dollie M. Murphey who married his g-grandfather, C. C. Peek and gave birth to his grandfather Jesse James Peek, b. 06-20-1894, Pryor, OK; d. 02-03-1954, Roswell, Chaves Co, NM.
Dollie is on the Dawes Final Rolls, pg 661, Census Card # 4652
They had their children listed on the Dawes Rolls too:
Henry C. Peek b. abt 1890
Grace O. Peek b. abt 1892
Jesse James Peek b. 1894
Susie A. Peek b. abt 1896
Richard Peek b. abt 1899
Edna E. Peek b, abt 1901
We don't have any information on any of the other children, only Jesse.
