I've found our family name spelled different ways, and likely changed over time. John McMullan married Margaret Orr in Downpatrick, Down, Ireland at the Church of Ireland Cathedral May 2, 1844. I have two records of this event which are handwritten records, probably by the person registering the marriage. I don't know where John was born, or even his age, unfortunately. On one record the name is spelled "McMullan", and on the other "McMullen". Then, after the family emigrated to Quebec, I found an actual signature for John showing the spelling: "McMullian" in 1847. The record was for the birth of his second Son, William John, and the Son was shown by the registrar or curate as "McMullen".
I have not seen too many spellings as McMullian, and was curious if the name could have been spelled that way for a reason?? Perhaps, a class issue, a way to identify with a particular religion, or??
During the time my Great Grandfather, William John McMullen lived in Fergus, Wellington County, Ontario he changed the name to "McMillan". I don't know the exact reasoning, but it may have been because there was another William McMullen living nearby, and perhaps he changed it to avoid confusion?
On different census records, I've seen the name spelled a lot of different ways, which seemed likely at the discretion of the census taker or the person recording the information.
