Hi. I have not got that far back yet with the ion family tree. But in my family it was pronounced EON. It could be my line as I have Benjamin Ions running throughout. and they do come from lancs and westmorland. My line runs through townson Ion who often was called William of Fowien (muddling) anyway so far his father was a benjamin ion from 1798 and his son was also Benjamin Ion 1865. Can I get onto your tree to check. many thanks Wyn
