I am trying to find the parents of Mary Barnes born about 1798 in Ireland (according to the 1850 Census, and the parents of Thomas H. Burton that I think was born in Pa. They were in both Slippery Rock and Butler. I am interested in two of their daughters. Mary Barnes Burton born Jan. 28, 1824 and her sister Sarah Burton born 1838. Mary Barnes Burton married John Young of Slippery Rock Twp, Lawrence Co. but later settled in Butler. Sarah Burton married Jacob Young and lived in Slippery Rock Twp. Lawrence Co. Her husband Jacob died early and Sarah spent a little time in Butler with her parents and in later life lived in Pgh. area with her daughters. I have been trying (dead end) to find the parents of Mary Barnes and Thomas Burton. Elsie
