The line I am following is Ann Indian born c1840 - parents William Indian c1813 Alston & Ann Hardy c1821 Kirkoswald - marr. 1837 Alston.
Ann Indian marr George Pattinson - 1865 Auckland Saint Andrew - Co. Durham and then William Forster 1874 Co. Durham.
According to the info that I have managed to find Ann c1840 must be sister to your John. I have collected all of the census' that are available but am interested in anything to do with this family especially earlier generations.
Cromwell, here is what I have using a variety of sources, sometimes only an index or census, as I don't yet have all the birth, marriage, and death records.
William INDIAN was baptized 09 Jul 1813 in Alston, Cumberland, England. He married Ann HARDY on 23 Nov 1837 in Alston; both fathers were named Thomas. William died 02 Dec 1871 in a mining accident in Auckland, Durham, England. I believe that it was Ann, his widow, who married William FOSTER/FORSTER (not sure which spelling it should be). The reason I say this is that if you look at the 1881 census in Tanfield, Durham, England, for William FOSTER and his wife Ann, he has a step-son Jacob. Jacob was the son of William INDIAN and Ann HARDY, and the ages fit.
Children of William INDIAN and Ann HARDY include:
1. Susannah INDIAN b. c1839, m. Thomas PATTINSON, no known children to them.
2. Ann INDIAN b. c1840, m. George PATTINSON, children include Jane Ann b. c1869, Susannah b. c1872, Mary E. b. c1875, Hannah b. c1877, and George M. b. c1884.
