Maddalin
Maddalin Origin and Meaning
There are many ways to spell Madeline — eight currently rank in the Top 1000, and many more make the extended charts — but Maddalin is a truly unique variation. It has never been given to more than four baby girls in a single year.
Regardless of what spelling you use, however, when you combine all the variations together, names from the Madeline family are given to nearly 10,000 babies every year in the US. Whatever spin you put on it then, there will still be plenty of other Maddys running round the playgrounds in the next few years, making it feel more like a Top 10 option than it really is.
Not necessarily a bad thing - it is a great name after all with plenty of elegance, sweetness and spirit. It's just worth remembering that tweaking the spelling won't make it stand out when its called.
