I have found my gr.gr.grandmother finally. Mary A. Clanin Brown remarried in 1881 to a Joseph E Mercer, in Fulton Co. She died in March 7 1905, buried in Summum Cem. where her son William G is also buried.  Until I visit again, I do not know if her first husband George Brown(gr.gr.grandfather) is there but figure so., but have never found a stone with his name.  Joseph remarried before 1910 to a Virginia ?. He died in Fulton Co.
Glad to have found her, but still looking for any info such as an obit.  She was married to Mr. Mercer for 25 yrs so perhaps some family member of his may have pics.
Thanks for any input!
