Regarding Mary Jane Jones; I found two Mary J. Jones' listed in the 1870 & 1880 Decatur Co., IN census. Both are born abt 1866. One is the daughter of John W. & Margaret S. Jones of Adams Twp., Decatur Co., IN and the other is the daughter of Louis C. & Ruth Jones of Washington Twp., Decatur Co., IN. If you want the info for both to see if you can determine which one is your Mary Jane, I will be more than happy to get it for you. I hope this info helps.....................Karen
