By 1870 Elias in no longer around and 56 yr old Letha and her 26 yr old son, Mathew ("M. P. Davis") are in Upshur Co., TX. Mathew has a wife and kids, the oldest who is a 10 yr old son born in Texas. Living next door, Letha has some kids also, the youngest being 6 born in Texas.
Based on all this, it appears they all were in Texas by 1860 judging by Mathew's 10 yr old son, and Elias probably died sometime towards the end of the war because his last child born in Letha'a household there in Texas was born about 1864...in Texas.
Also, wondering if Mathew served in the war. He would have been about 17 years old at war's start. Elias would have been 41.
If anyone can find any war service info on either Elias and/or Mathew Davis based on these ages and info I've given, it would be very much appreciated!
Thanks, Kevin.
