Philemon Bancroft

Looking for information on Philemon Bancroft born West Yorkshire area around early 1800's.

Trying to find out if I am following the right line. John Thomas Bancroft born Rotherham 1878 (I believe this could be my grandfather), John Thomas was the son of John Bancroft (who was Philemon's son) born Lightcliffe, Halifax abt 1845, he married Sarah Walker (born in Scotland). John (b 1845) had a brother Joseph and I know they lived in Hull area for a number of years before John ended up in Rotherham area where John Thomas was born.

John Thomas possibly married Fanny Martin in 1901 in Sheffield but later in 1920's I believe he lived with my grandmother who as far as I can tell was Sarah Jane Shakeshaft (who married Joseph Legdon) before taking up with John Thomas Bancroft. The odd thing is, is that Sarah Jane decides to call herself Fanny Bancroft (nee Smith) on birth certificates of the 3 children she had with John Thomas Bancroft but I do know that her other children including 3 of my aunts were Legdons.

It is a very tangled story which I am trying to unravel, does anyone have any information on the family which may help. Thanks Anne
