different name meaning the same?

to the group:

In my research I am confused about my gmother's name. In her Bap. it reads Teodora. In her church record it reads Maria Dolores. In different bap. records of her gkids it either or, Is Teodora the same as Maria Dolores is my question? Also there is mention about the 117 families sent to los Altos to colonize the area, in the forum posting recently,can one tell me where I could buy books or articles on the subject.

Also what about misspelled names on Familysearch.org, how to correct. Appreciate any info.
