Gail,
Sorry, but I don't think any of your WHITE's are in the book. There are no COTHRAN's in the book. As for WHITE's, here is some of what's there:
p. 422 John W. WHITE and son
Emory Owen WHITE (b. 12 Aug 1882, AR)...also two siblings of
Emory.
p. 423: John WHITE (different than above) (b. 1813), son is Henry
Clay WHITE (b. 15 Jan 1854,
LA) (many other siblings of Henry
Clay included)
p. 425 Tyler Taswell WHITE m. abt 1850 Samantha Jane STANLEY, son John WHITE m. 1902 Willie BAILEFF
Many other WHITE's are mentioned, but most are more recent (b. aft 1880). There are also several WHITE's included in other sections of the book (per the index) that I haven't gone through--but I doubt if Mary Ann is included since the
COTHRAN surname is not in the book. (The index only has surnames).
Good luck!
Jim
