Hi Gary.The spelling will vary from place to place. I have found in the documents of my Elzey ancestors from Southampton, Hampshire, England that in the same document it may have several spellings, such as Elzey, Elzeye. I've seen Elzie and Elseye as well. But in most of my Elzey's documents ELZEY was used most. So two "l"s don't surprise me either. While researching this name you will see it spelled various ways. Even in the same family some spelled it differantly. Confusing huh! This is what they mean by Soundex = various forms to spell the same name in differant ways.
This was told to me when I first started doing my families research. Lets say an ancestor was boarding a ship to come to the new world. He couldn't spell, not write. So he told his name to the person who checks in the passengers and he spells it the way he knows how. This is the offical ships records. Spellings will vary.Sometimes folks will either shorten or change their surname completely when they arrive....makes it someimes harder to sort out. Good luck. Howard
