I am also looking for information on Lewis Gratis Adams's Ancestors. While I do not have any information on them I do have some information about the man that might help.I have his birth on October 8, 1835 in Raleigh, NC. (The date is correct but the location may be wrong.) Death was September 12, 1912 Kountze, TX in the Old Hardin Cemetary (verfied).His wife was Laura Mansfield Anthony (We think she is sister to Susan B. Anthony from family lore). She was born 1844 in Alabama and died 1937 in Kountze, TX also in the Old Hardin Cemetary. Here is a link that supports the birth and death dates http://www.rootsweb.com/~txhardin/military/csa_pensions.htmhttp://www.rootsweb.com/~txhardin/military/csa_pensions.htm
From my research he may have also spent time in Bluff Springs, FL as this is where his son (my great grandfather) was born (he also died in Kountze, TX though).
Hope this helps some and if you have any information not listed I would love to look at it.
