I've been trying to put together a gaggle of these folks in a way that is correct and makes sense. Some of what I have I know for fact, some has been "assumed" because they were in the right place at the right time, etc. If anyone is related, I'd love to hear from you, and if you see any errors or new info, I'd like to know that, too. Thx!
Solomon Poston & Bethenia Roberts son Peter H. Poston married Elizabeth L. Gibson on 28 Nov 1867 in Sullivan Co., TN. They had the following children: Adaline Martha, Sarah, Jane, Barthena "Bertha" and George M.
Adaline was b. 1865 (before Peter & Elizabeth's marriage). I consider it possible that she's Elizabeth's daughter from a prior relationship, though she went by the name Poston. Adaline married John Mosley/Mosby 4 Aug 1879 in Sullivan Co. They were in Washington Co. during the 1880 census with John's son Baker from a prior marriage. Family lore has it that Adaline had 3 children with him, one of which was a daughter named Mandy who died during WWI.
On 19 Aug 1895 in Hamblen Co., Adaline married Samuel Phillips and had 10 children with him before their separation around 1915.
Adaline's sister Sarah (b. abt 1867) married Samuel's brother Young B. Phillips (b. abt 1858) on 7 aug 1891 in Hamblen Co. I believe that they had a daughter Mabel. I don't know if they divorced or if Sarah died, but in 1903 Young was remarried to Dora.
The sister Jane I believe went by Jennie and married John S. Keys (b. abt 1845) on 25 Oct 1892 in Washington Co. In the 1900 Jennie and John had a niece Mabel (b. Feb 1894) living with them.
The remaining sister Barthena "Bertha" was m. about 1902 to a Mr. Penix. In 1910 Bertha was living in Spokane, WA with her daughter Bonnie (looked like Bonsi on the census?) and her widowed mother Elizabeth Poston. Bonnie's last name was given as Penix, even though she was b. abt 1895 (7 years before Bertha married Penix. So I'm not sure about that. I can't find any other info on Bonnie or the Penix husband, but in 1920 Bertha is married to John M. Krogh, a man who was her boarder in 1910. They were living in Union Gap, Yakima Co., WA. By 1930 John was a widow, living with his son's family in Oregon.
I'm unable to find any record of their brother George M. (b. abt 1877). I don't know if he died young or if I'm just having a hard time finding him.
