William a Walker Mary Walker Mary Ann Walker Alice B Walker

My great-grandmother, Mary Ann Walker Crocker, was the daughter of William A. and Mary Walker. Mary Ann was born in 1875 in Missouri. Shortly thereafter, the family came to New Mexico because Mary (elder) had tuberculosis. In 1879, another daughter, Alice B. Walker, was born in New Mexico. The family appears in the 1880 census.

I know that Mary Ann went to live with the Crocker family and in 1892, married my great-grandfather, George Ely Crocker. I was told that her mother had died and that her father had gone to Galveston, Texas, and never returned. I have no idea what happened to Mary Ann's baby sister, Alice.

If anybody out there can help me in locating the missing Walkers, William A. and Alice B., please let me know. Also, if you can tell me when Mary died and if it was from tuberculosis, I would appreciate it. In fact, I would appreciate any information about them at all.
