Good Morning David: I did not find a birth for Lewis Shumway in Oxford. I did find a birth for Lucy not named Smith, but ALLEN with the date of birth that you indicate as follows: 1779 ALLEN Lucy, d. Zachariah S. [dup. Zecheriah Smith] (b. Elizabeth Town, N.J.) and Joyce (Athearn), Jan. 25, 1779. Tisbury, Dukes, MA. This is from the on-line vitals at NEHGS available to members. I am not saying that this is the correct Lucy you are looking for, only that this is what I found. I have own copy of the printed vital records of Mendon, MA to 1850, and I did in fact look at them for Lucy. Nada. Regards, Alison Franks Archivist, Rawson Family Association
