angelamarie100's list "Future Baby #3" of 2 great name ideas: Macsen - Windsor!

Future Baby #3

I have 2 children right now and am looking forward to adding one more someday. 
My boy is Castor George: Castor was a strong, uncommon name with little-to-no nicknames. George is after my maternal grandfather. There has been a "George" in every generation of his family. 
My girl is Scarlett Eugenia. Scarlett is a strong, bright, classic girl's name. It also has some of the same letters and sounds as Castor does. Eugenia is after my paternal uncle and godfather, and it is my maternal grandmother's middle name. There has been a "Eugene" or some form of it in every generation on my father's side. 

For our third I would like to stick to the older more classical names, but would not rule out very uncommon names. We caught a lot of flack for naming our son Castor, but we love it and it fits him well. He is certainly one of a kind. I'd like a name with similar consonant and vowel combinations. 

Macsen may sound like a modern invention, cousin to Jackson and Maxon, but it's a longtime Welsh variation of Maximus with evocative roots in legend.  Macsen Wledig is another name for the Roman emperor Magnus Maximus, was played an important role in Welsh history and was further immortalized in a poem celebrating his dream about his lover Elen.  Macsen also appears in Arthurian legend.

Windsor may have male references, such as Britain's royal House of Windsor and a tie's windsor knot, but this name also has a definite feminine feel, as in Windsor Rose. That seems appropriate, as Windsor is used equally these days for boys and girls.  <br/><br/>Nicknames might include Win, Wind, Windy, and Winnie.
