I have a Swedish man born before surnames were standardized. He was baptized as Peterssen but changed it to Svensen/Swensen as he came to America, and later to Swanson. How do I note these changes so that his life records and events can reflect his evolving surnames?
If it had remained variations of Peterrsen it would be obvious, but the change to Svensen/Swensen is less obvious. And, yes, this is the same man.
