I'm searching for the names of Margaret Steenbergen's parents. I believe her mother may have been Mary Steenbergen. The 1840 Monroe County Census lists a Mary Shinburgin with no males and number of females as: 1300001. The 1850 Monroe census lists Mary S. Burgon, age 43 with evidently her daughters, Margaret age 19, Mary age 17, Elizabeth age 15 and Nancy age 13. I believe Mary's last name was misspelled on both these census records. Possibly Mary's husband was William Steenbergen.
Thanks in advance for any help.
