George and Margaret Sedgwick with daughters Jane Anne and Elizabeth arrived at New York on July 5, 1853 aboard the ship Australia. Port of Embarkation was Liverpool, England, and their point of origin was Durham. Note that her obituary says 4th of July 1849, but they were still living in England at the 1851 census.

The 1851 England census puts his birth place as Sadberge, Durham, England. He was a shoemaker. The 1841 England census finds him living in Hurworth, Durham and working as a shoemakers apprentice.7a

Margaret's maiden name, Bowser, is listed on the death certificate of Thomas S Sedgwick.7a
