On familysearch there is a baptism for one Gulielmus Ambrocius Dewson. His parents are Frederici and Annae Dewson. I know that Frederici = Frederick and Annae = Anne. I also know that Gulielmus = William but for the life of me I can't work out what Ambrocius is. Google just asks did I mean Ambrosius? could it just be a spelling mistake or is there such a name as Ambrocius? Any thoughts welcomed.
