Mary Leighton Fish
born April 1828–April 1829
  in Yarmouth, Norfolk
died very roughly 1898

In the 1881 census, Elizabeth Lowrey (née Fenwick) has a young nephew, Frederick Fenwick, in her household. As he has the same surname, he is presumably the son of a brother of hers. Frederick Fenwick can be found in the 1871 census living with his mother, Mary Fenwick, and grandmother, Mary Fish, among others. The only marriage between a Mary Fish and a Fenwick at about the right time involves John Fenwick (Yarmouth district, December quarter 1857: 4b39).
