Baptisms for children of a Thomas & Martha Tune
Elizabeth 5 Mar 1855 Holy Trinity Parish, Hull
Phoebe 15 Jul 1857 Holy Trinity Parish, Hull
Ann 16 Dec 1860 Holy Trinity Parish, Hull
Martha 6 Feb 1863 Holy Trinity Parish, Hull
Martha 24 Jan 1872 St Johns, Hull
Now a possible Birth for a Thomas Tune...with a Thomas father..
Thomas Tune 25 Feb 1827 Epworth, Lincolnshire
Father Thomas Tune Mother Phoebe
...it could be that Thomas and his family moved to Skipwith when he was very young and he believed that is where he was born, OR he could have been - then baptised at Epworth, maybe that is where his mother was from??
there is also a Thomas Tune on 1841 census for Epworth age 14 !!! and another at Crowle age 20!!
All the above are from familysearch.org
