My BARTLETTs are in WV.I am Admin for BARTLETT-DNA Project and have gotten involved in many different BARTLETT lines.For the past e years I've been extracting BARTLETT from all of the census records (once done, it will make things a LOT easier for BARTLETT researchers). I've got most done for VA, WV, NC, SC, GA, TN, KY, AL, AR and recently MD; and I've got some for other states.When I try to trace families like your's, it adds more to my database.
Here is the info I have found on your Louisa BARTLETT:
Louisa BARTLETT? b 1870 TX [par b TN/TN]; d Newton Co, TX; mc 17 Jul 1891 Polk Co, AR Jesse L HOCK b 1870 AR >[TX:H0]

1. Ethel HOCK b 1896 TX [H0,J1] 2. Ollie HOCK b 1898 TX [H0,J1] 3. Elma HOCK b 1905 LA [J1] 4. William L HOCK b 1907 TX [J1] 5. Ada HOCK b 1909 TX [J1]
So clearly Louise and Jesse were living in Polk Co, AR from 1880 to 1891 when they married.
I don't know if there is any relationship with John and Martha CLARK who took in Orphan Louisa BARTLETT... but they report that she was born in TX.There should be some documents on this, perhaps in Polk Co, AR.
I hope this helps - please let me know if you find out anything more.
