Just read your posting with a great deal of interest as we have recently managed to push our line back another generation and added a Prestwood to our tree. We have a Maria Prestwood marrying a William Clipsham July 1836 in Bardney Lincs. Williams parents were William Clipsham and Elizabeth Stamp.
We have been unable to find any information regarding Maria Prestwood and wondered if you may have come across this lady in your research. The only Maria of the right age we have found was born in Shropshire, which seems a long way off unless there is some family link between these locations.
