Melissa - I like to sort out BARTLETT lines through census records, but your's has me stumped...
I can find James BARTLETT 35 Farmer b MO par b IN/IN and wife Mary 31 b AR, par b TN/TN in 1880 Wilson Co, TX (Stockdale) census page 79D.It looks like their children are Andrew 12; Rachel 9; Sarah 7; Mary 5; and William 1 all b TX.Living with them are nephews and neices.
I cannot find any of these in the 1870 census, anywhere.
I do find a Sanders H BARTLETT 41 b PA and wife Nancy 23 b IL in 1850 Pike Co, MO census with chldren William H C 18; and James 12 both b MO. Sanders BARTLET 54 Tobaconist b MO and Nancy 32 b IL are there in 1860; and S H BARTLETT 63 Tobaconist b VT and Nancy 43 b IL are there in 1870, along with Jas T BARTLETT 13 b MO
There is also a Physician E M BARTLETT b 1803 in MA or ME in Pike Co, MO 1860 and 70 with children.
But I cannot seem to make any connections.Do you have any other clues that would help put these in perspective?
