Hi, Amy. I have a Lucy Ann Nickerson who married Ephraim Mason in my tree -- I am related to the Masons.
From what I can gather, her father Charles Nickerson, Sr. was married twice -- 1st wife -- Susan Smith -- sons James b. 1790, Jesse b. 1792 and Nathan b. 1798 and daughters Sarah b. 1800, Elizabeth b. 1789 and Susannah, died 1821. His second wife was Elizabeth Smith and their children were Charles Joseph, Jr. born 1814 -- he married Margaret Sangster, Lucy Ann b. about 1810 and married Ephraim Mason, Rebecca born about 1810 and David (d. 1836).
This info comes from other family trees as well as census records but needs to be confirmed.
Hope this helps a little. You might be able to find more info through death records, etc., at
