I am also the gt gt granddaughter of Orson Laurence who was married to Mary Arabella Allen.I too have been searching off and on for Orson's parents over many many years.So has another cousin, Christie Ingham who made mention of one of Orson's sons, Elisha Randolph Laurence in another genealogy.com thread.Christie's parents spent considerable time looking for Orson's parents as well. I wanted to let you know of my presence here and perhaps we can exchange notes.My maiden name is Laurence.My dad always said his grand parents spoke of the Laurence lineage as being French. Pronounced LA Rance. Is it possible they were French Canadian or Acadians who were thrown out of Canada by the English and who may have first settled in NC followed by more southern states? I have in my records MARY Arabella Allen, as well. Some of the family just has her as Arabella.It is good to know her father's name.
