The surname for one of my female ancestors is shown on her New Zealand marriage record as Aplin, and her father's surname is the same, and it's also Aplin on his Welsh death record. She was born in Wales and her parents' marriage record shows his surname as Appling. I am not sure I've found the correct birth record, but if I have, it is Apland.
Could someone please confirm that I should give her a birth surname of Apland and he a birth surname of Appling, And then, how should I show their changed surnames for his death and her marriage? I'm concerned that we need to make sure that when someone else is uploading them in future, perhaps with a different version of the name, that the matches are found.
