Looking for any information on a Mary Willson who married a Richard Bretherton/Brotherton 1790. I don't know where Mary Willson was from originally, but son Richard was born in Warrington, Lancashire abt 1806. There is another Richard Bretherton born same time and died Warrington in 1820's - my Richard emigrated to Australia in 1849, after spending some time in France and London. Mary's other children include Sarah,Jesse,Samuel,William Bretherton. Thanks.
