Something to consider, Debbie, is that at that early period - and for quite some time afterward - the names "Alice", "Anne", and "Agnes" were frequently used interchangeably. (Occasionally you will find the same woman referred to under all three names, depending on sources.)
It wasn't until Dr. Sam. Johnson in the 18th century that spelling (especially of names) became fixed and immovable - and at that the Americans had to wait for Noah Webster in the early 19th century (he's the reason for the differences between English and American spelling).
