I've come across lots of variants like this. See the Skelcher/Skelcey thread to see how one name mutated from the former to the latter, one branch eventually becoming Kelsey. Stanley sometimes acquires a D - Standley. Some Lynes are not related to me because they were originally Lyons, mine were not in recorded history. The name Gyde was originally pronounced "Jyde" according to some records, now it is always "Guide". Nothing surprises me any more.
Forenames also get confusing transcriptions - I've seen Phobe for Phoebe, Lousie for Louiise, and Sibly (transcribed Silly!) for Sybil. These three rival the Bristolian girls Evil, Idle and Normal!
