My family research has gone through two phases already. In the first go around it appeared that my William Harrison was the son of William Harrison and Elizabeth Alcon of Glaisdaleside in Egton township. But then the prayer book of Elizabeth Underwood, daughter of William Harrison and Elizabeth Alcon, came to light clearly showing that her brother William died in Egton in 1848. We now have determined that that William Harrison was actually married to Mary Webster.
That caused me to reexamine the place of my ancestors in the larger Harrison family tree and after considerable research and weighing all the alternatives it appeared that my William Harrison was the son of Joseph Harrison (brother of William Harrison who married Elizabeth Alcon) and Mary Readman.
In 2015 I had my Y DNA tested and in 2016 tested a direct male descendant of William Harrison and Elizabeth Alcon in what I thought would confirm my place in the family tree. However there was no match. So barring any undisclosed adoption or other anomaly it looks like there is more than one Catholic Harrison family from this part of Yorkshire and not one as originally thought. (William the son of Joseph Harrison and Mary Readman actually married Mary Consit and later Christiana Dale and lived at Struntry Carr Farm)
So the search continues. More research in the communion and confirmation lists of the the Roman Catholic churches of Egton Bridge, Ugthorpe and Whitby await, as does the search for direct male descendants of other Catholic Harrison lines to test and compare Y DNA with. If you are descended from a Catholic Harrison family with roots in the Egton/Glaisdale/Lythe area of North Yorkshire I would love to hear from you.
