I am searching for the line of my third great grandmother who was MARY ANN PARKER married to my third great grandfather ISAAC LAY I. They were in Natchitoches PARISH and later DeSota Parish. Later, several of his sons were in Bossier Parish around Bellvieu. Isaac Lay I and Mary Ann Parker Lay at least had these children: Nancy Lay Wallace (married to Maxmillian Wallace), Elizabeth Lay Lafitte, (married to Severe Laffitte), Isaac Lay II (my 2nd.great grandfather married to Mary Adelaide Allen, a sister to C. C. ALLEN), Benjamin Lay, Thomas Lay, and William Lay. I believe that the Lays had come from Tennessee to Louisiana around 1830. I do know that my 2nd great grandfather was ISAAC LAY married first to MARY ADELAIDE ALLEN. They had five children: Sarah Louise Lay Boykin (my great grandmother married to Thomas Gordon Boykin), Mary Elizabeth Lay Robertson, Nancy Adeline or Adelaide Lay Swann Neeson, John Franklin Lay, and William Jefferson Lay. William Jefferson must have died at age one or two years old. ISAAC LAY II married second to Elizabeth Jane Perrett. ISAAC LAY II died in 1859 and Elizabeth Jane died in 1860. After this, ELIAS O' NEIL (I believe an uncle to the children by marriage to their mother's sister) became the tutor for the children. Can anyone help me out with this PARKER LINEAGE or ALLEN LINEAGE. Also, I need to find parentage of ISAAC LAY I and where this lineage was prior to 1830. Any help appreciated.
