I have a fairly comprehensive listing of North Shore Langille's and I find a William Langille (b. 1811-son of John Louis b.1775 and brother to John George) married Lucy Langille and had the following children: Ephraim (b.1824, m.Lois MacDonald 1868) Mary (b. 1841) Margaret (b. 1843) Silas (b. 1846, d. 1847) Susan (b. 1850) Martha (b. 1853) Ellen (b.1860) Caselda (b 1862) Johan (b. 1864) Do any of those names fit? I also have a listing for a Lucy Langille b. 1820 to John George Langille(b.1773, d. 1864) andMarie (or Mary Margaret) Perrin.There are no descendants listed for this Lucy but she is shown to marry a William Langille (date unknown).
