Alex. Shaw and his wife Anne Elizabeth (Blanchley?) had three children christened in the parish of Malew around the time that Lieutenant Governor Alexander Shaw was in Office.
Augusta Shaw was Christened 1795 and in 1821 an Augusta Shaw married Samuel Flood Page in Preston Leicestershire. He was the son of Samuel Page and Mary A. Flood.
There is a record of Henry Watson marrying a Mary A Page in 1851.
It's all a bit vague but there may be something here to work on.
