Name change for Janet Sweenie to Janet Swan MM3Y-XX2
Please help me to understand why my great grandmother's surname, which appears as Sweenie on my grandparents marriage certificate, but according to Family Search info, is actually Swan? Family Search profile MM3Y-XX2 Janet Swan. How can a surname change? It seems that the info tallies with what I have, but how can I be sure? I don't have much info on her, which would make things much easier. This name change happened with another ancestor of mine, and I took a chance and changed her name from Margaret Scott to Scolick, and it turned out to be right! I'm really stuck with this, and I would love to know more about this branch of the family. Your help would really be appreciated. Thank you so much.
