Re: Boydston Cemetery-Texas

Benjamin and his sister Mary Ann Boydstun Butler were close in the family . Mary was the next in line after Benjamin, born in Dec.1813.
In the 1870's she traveled to Rockwall,Tx. to see him. We know she traveled from ILL. with her son J.B., her step-daughter, Mary Butler, and her eldest sister, Sarah. Sarah had been living with Mary Ann Butler's family in 1860 in Ill. before arriving in TX.
I know Mary Ann and her son, returned sometime in 1880 to Warren Co. ILL. to tend to family matters. Her only child, JBB, on his return back to Texas lived near/with his Uncle Benjamin and his family.
I can not find any records to prove where and exactly when Mary Ann died. Their mother, Nancy, is buried in Knox Co.ILL. as well as others from this family.

Does ANYONE in our Boydstun's have any knowledge [proof?] on Mary Boydstun Butler perhaps listed in a family Bible?
