Best bet, but it is by no means certain, is that Martha Jane was a daughter of William and Martha (Porter) Broyles who married in Brown Co. in 1851. William was born in 1829 in TN. His father was John G. Broyles, son of Thomas Broyles of White Co., TN. John G. has not been located in the 1840 census at all, but is in White Co., TN, in 1830 and in Brown Co. in 1850 and in Laclede Co., MO, in 1860. In the 1850 census he is (somewhat remarkably) listed as James Broyles, not John, but his wife is named Mildred, an unusual name for the time period. John and Mildred and their son James are in Laclede Co., MO, in 1860, the county to which John's father Thomas had moved prior to 1850. [All of this is my way of justifying the unusual step of making "James Broyles" of Brown Co., IN, the same as "John G. Broyles".] I have not found William in the 1860 census, so I can't confirm he had daughter Martha Jane. If someone can find them in 1860 Brown Co. census, you'd have your proof. The following web page has info on Thomas. You can click on son John G. to get to William. http://www.ultranet.com/~deeds/broyles/html/d0004/g0000036.htm#I190
