Marguerite would be absolutely gorgeous with your daughter's name. I'm kinda' hoping you have a girl...
Winslow and Frederick would fit well with her name as well. Winslow Frederick would be my choice actually.
What's your daughter's name?
Out of your list I like Winslow the best!
I'll also suggest-
I don't think you can go wrong with Oliver, William, Henry, and Oscar. Are you in the UK? Those names aren't so popular in the U.S. -- I know one Oscar, one Henry, one Oliver, and one William (and I have three kids and work in the schools). I worried a lot when we named our first two (Alexander and Madelyn) because both names were in the top 20 at the time. But my Alexander goes by Xander, and the other Alexander in his grade goes by Alex. So no problems there. Madelyn goes by Maddie. She's never had another Madelyn/Madeline or even a Madison in her class, but she does have Adalyn, Adalae, and Addison that all go by Addie. But she's the only Madelyn or Maddie. Honestly it hasn't turned out to be as much of a problem as I thought it would be. If you really love a name, you shouldn't let worries about its popularity keep you from using it. :) Good luck!
From your list I like Rafael, Rafe is a great nn for this day and age. I also like Oliver and Winston.
I do not know if this will help any but when it came to names in my family (Dad, Mom and me anyway) we went with more unusual names for the girls and more solid classic for the boys. I am Tamara (it was unusual at the time and hit a popular streak for girls my age!) Tannia (pronounced Tanya) My brother is Richard. You can see from my sig what I named mine. My sis only had one child, named him Travis. I think my brother went more unusual for his boy Walker and solid on the girls Julie and Shannon.
My nephew has three boys, Jason, Shane and Emmett.
It's amazing how different the popularity lists are between Australia and US. I'm planning to name my son Oliver, but it's only 78 in the US - which is not as popular as my first son's name (Julian), and I've only met one other Julian since naming him. But I agree that in Australia or the UK, it might be too much. And it makes me wonder if Oliver is going to keep going up fast here in the US too!
But ... your edited list has some really good choices. I love Winslow - classic but totally unusual. And 'Win' on an older boy or 'Winnie' on a little guy would be great. Good luck! :)
I really, really love ALL of these names. What is your daughter's name? It's a lot easier to love a name when it fits with your family.
My favorites are Raphael, Arthur, Walter, and Winslow.
I love Arthur and Walter for their solid, peaceful feel. There's something about these outmoded names that makes them charming on little boys— maybe it's the fact you can envision the men they'll grow into, or maybe the contrast between dusty name and spritely little boy is simply fun to experience. Your son won't know many other Arthurs or Walters, but when he opens books and sees his name, maybe he'll be inspired by the legacies of the Arthurs and Walters before him. It will give him a sense of a connection to the past that his peers might lack. Personally, that's why I love these names. If you haven't considered it, think about Frank as well.
Raphael and Winslow are simply cute, fun, and come with great nicknames.
Have a brother called Francis-he wears it well....
