I'm wondering if anybody else has come across something similar.... I.E. multiple census listings for the same people? In 1880 my great grandfather is listed (aged 9) as living in his father's (James) house in Newburyport, MA, along with six siblings and his mother, Isabella. Also in 1880, but in Salisbury, MA, he is listed again (aged 9), with all of his brothers, a mysterious Isabel and his mother listed as Isabel also. I know from a 1900 census that James, Isabel/Isabella, and one of their younger daughters were living in Salisbury in a house James may have owned. Now there are a ton of questions, mainly, why two homes?
Have you found anything similar?
