Name changes amongst a family

Question

How should I handle when the last name changes from one generation to another (I.E. father spells last name one way, then son and future generations continue another spelling).

Comments

The last name at birth (LNAB) is what they were named at birth, if the name changes in their lifetime then this should be shown in the current last name (CLN).  Usually this will just happen to one generation (though it could happen again in subsequent generations).

Sometimes census enumerators or clerks misspell a family name and this is something else and is more of a historical typo rather than an Also Known As, in those cases a mention in the biography could be made.

Answer 1

I use the other last names so it shows up "aka".  I have numerous name changes DiFranco became DeFranco, Lauzon became Lauzau, etc.
