SARAH DREWETT Was a witness to the marriage of my great,great Grandfather William Drewett B abt 1808. to Jane Newton B abt 1811. married at Holy Trinity Clapham London on 31 Oct,1831. SARAH may be William's Mother or Sister.Various Trees have different parents of William none of which are confirmed. SARAH i believe is the clue to extending the tree beyond 1808. Grateful thanks for any information. John.
