My GGrandmother was Ann (Garatt or Jaratt) Marrow who was born abt. 1850 and died aged 80 years on 29 March 1930. I have not yet found her birth or marriage certificate. She married my GGrandfather William Jones from Birkenhead abt. 1870. He was a Fishmonger of 81 Exmouth Street Birkenhead on the 1881 census, he died on 24 Feb. 1886. They had 5 children Elizabeth Ann who died aged 4 years on 26 October 1874, Melvina, Margaret J, William J and my Grandfather John Marrow Jones. Could this be the Ann Marrow that you are looking for?
