Also don't forget the Dutch for example. I have three different families with 4-6 different spellings of their names. Most of the Emigrant's sons took a different variation of their surname which makes it confusing and also causes repeats of people in you tree. In fact I have a mess to clean up that I found today, after looking at you Tips for the day because I have one family with 4 different surnames. and if I was to check the index to see if I have a spouse already to attach, I would enter another of the same person.To keep from repeating people, I use the father's name first and put their in quotes and note their page they are using the surname in quotes not their father's.
