Thank you, Anne. I think you may very well be right.
John Mitchell married Ann Flather at Halifax on 25 Sep 1824. Ann was baptised at Congregational Or Independent, Northowram.
John and Ann's first child, Emma, was baptised at Sr Mary's Church in Rastrick but their second chold, Martha Grace, was baptised at Bethel Methodist New Connexion, Brighouse.
Their third child, Ann, is my GG Grandmother but the family had moved to the Holmfirth area by this time as she was baptised at Holmfirth and the family were living at Magnum in the 1841 census.
My reason for think John may be related to Samuel is that he was also born in Rastrick but married Ellen Brook at Kirkburton on 26 Dec 1831 and they were also living at Magnum in 1841.
