There was a baptism of a Sarah Ward to a George and Sarah Ward, at Bolsover in 1809. Not yet proven whether this is the same Sarah Ward who marries Robert Ranshaw (spelled Renshaw on the marriage entry at Bolsover in 1821)
There was also a baptism of Sarah Ward in Bolsover in 1799 to George and Elizabeth Ward, and this seems to be the most likely to be the one who married Robert Ranshaw in 1821.
