To Mr. Minch:
Hi, thank you for offering to check. I haven't been successful so far, as my family is apparently not listed in the Barbour Collection.

But my ggg grandfather was Daniel Somers (or Summers) Lacy (or DeLacy, DeLacey, Lacey), born 1815 in CT (if he had his birth year correct), with both parents also having been born in CT. I cannot find his birth record.

Names common among his children and grandchildren may be clues to his siblings--
Charles, Russell, Mark, John, Howard, William, Israel, Isaac. He had a daughter Ann Elizabeth (possible clue to his mother's name).

Thanks again, for checking what you have.
