I don't know why you keep saying she has a different husband and date. While I can see the web page has TWO marriages for her (which I did not yet sort out), ONE of those is the proper one you cited. I also notice the web page calls her Lucy Keaton SANDRIDGE but makes absolutely no mention of how she got a different last name than her father (James KEATON) and so based on that I think the information is erroneous or there's a marriage not listed here.
Or, they're two different women and his web page is screwed up (not impossible but he does cite his sources, did you check any of them yet? I haven't had time to)
Lucy Keaton SANDRIDGE Born: 7 Apr 1778, , Orange, Virginia, USA Married (1): 13 Oct 1796, , Orange, Virginia, USA Married (2): 27 Dec 1808, , Monroe, VA Died: 10 Jan 1859, , Lawrence, Ohio, USA
Other names for Lucy were KEETON, , SANDRIDGE, and KEATON,.
Ancestral File Number:CXDL-S5. User ID:77.
Lucy married Elijah Grant SEAMANDS Sr, son of Private Jonathan SEAMANDS, on 13 Oct 1796 in , Orange, Virginia, USA. (Elijah Grant SEAMANDS Sr was born on 1 Oct 1777 in , Albemarle, Virginia, USA and died on 31 Dec 1862 in , Lawrence, Ohio, USA.)
Lucy also married James W MANN on 27 Dec 1808 in , Monroe, VA. (James W MANN was born on 29 Aug 1787 in , Greenbrier, VA and died on 13 Nov 1855 in , Monroe, VA.)
Also the Lucy Keeton Sandridge on his page has the wrong siblings. But that just means then I still cannot find proof she exists.
