Food for thought.
John Thomas Marr. Mar 1875. Sculcoates. Mmn Hopwood
Annie Marr. Sep 1884. Sculcoates. Mmn Hopwood
Annie Marr/Benjamin Seaman. Sep 1907. Sculcoates. (Confirmed mmn of daughter)

Also:-
Anthony Marr. Dec 1880. Sculcoates. Mmn Hopwood.
1901/1911. Anthony Marr, b c 1881 Hull, in household of Patrick Marr, bc 1839/40. Ireland. Sarah Marr, bc 1840/48. Dunnington, Yorks. Also present Robert Hopwood, bc 1856/79. Dunnington, Yorks. Living Sculcoates.

Have yet to find family 1881/1891.

Many thanks, brentor boy - this looks as though the name really was MARR, but John Thomas wanted to be different.
What chance do we poor genealogists have??
