1.  Marriage Record:  my understanding is that the Sullivan County marriage books were lost when the Sullivan County Courthouse burned down in 1853; and, certainly, I have found no source of pre-1853 Sullivan County marriages.  But a file at WorldConnect cites "Sullivan Co., Indiana, Marriages, Book 1, Page 52" as the source for the marriage of Joseph TRIMBLE and Catherine CARRICO on 28 Jan 1823.  It may be that some fragmentary records survived, as is often the case in a fire.

[unreadable] Josiah Carica Trimble Born August 8th 1835 Katherine Trimble Born October 21st 1839 William M. Trimble Born Sep 4 1844...

Harriet Trimble Born Decr [torn off]

The page goes on with some "Wisdoms" in small text that I can't deciper in the photostat, but which doesn't appear to have genealogical significance. Harriet's name appears to have been added later, in the space to the right of the other children's names, which suggests the "Record" was written after the birth of William, in Sep 1844, but before the birth of Harriet, in Dec of 1846.  The elaborate script and ornamentation suggest such a date would be reasonable.

9.  There is said to be a Trimble Bible in the possession of Mrs. Tessie James Miller (536 South Hope Street, Biola Hotel, Box 325, Los Angeles, CA 90017), at least, as of 13 Sep 1973.
