At the time of their marriage, Daniel was "of New Bedford, s/o Timothy of Westport and Phebe, deceased"; Sarah was "of Westport, d/o Humphrey, deceased, of New Bedford, and Rebecca." (Dartmouth, MA, vital records)
In the 1900 Federal Census, Ephraim G. & Emma R. Akin are living on Babbit St., New Bedford, MA. They have three children: Frank S. 15, Alice R. 11, & Sarah R. ?. Also in the household is Charles Hicks, 66, Emma's father.
In 1910 the family is still there: Ephraim is 48, Emma is 50, Frank F. is 26, Alice G. R. is 21, and Sarah E. is 16. Charles is no longer with them, so probably he has passed away.
I have not been able to locate the family in the 1920 census. However, in the 1921 New Bedford City Directory, Ephraim G. & Emma Akin are living at 11 Babbitt St., along with son Frank S. Akin, who is an electrical instructor.
