in the household of William B Calkins:
Julia A Sweeny, age 27
Electa A Calkins, age 3, born in Massachusetts
Louisa J Calkins, age 2, born in Massachusetts
Charles M Sweeny, age 0, born in Massachusetts
It is possible that William Calkins was the father of Electa, since Julia was living in his household by 1850, and they presented themselves as a married couple as early as 1853 when their son Munson was born. It isn't clear why Julia's name and the name of her youngest child are Sweeny, as her marriage to William Calkins was supposedly her first (as stated in the marriage record).
