My earliest known Lock ancestor is Daniel Lock who married Jane Tyndall/Tyndale/Tendall on 5 February 1798 in Minchinhmpton, Gloucestershire, England. There is a possibility he is the same Daniel Lock who was baptised on 6 October 1775 in Crudwell Wiltshire, the son of Jane and Joseph Lock. This is yet to be proven however.
Children of Daniel Lock and Jane Tyndall, were all born in Minchinhampton;-
Ann 1799-1877
Anna Maria 1801 – 1858
Joseph 1803 – 1835
Daniel 1808 – 1828
Samuel 1808 – 1879
John 1811 – 1883 my great great grandfather
Martha 1821
