Aside from Martha Louise's daughter, I don't think I've heard of anyone of the present era being named for Queen Maud. It's such an old-fashioned name. Did it ever surface anywhere in the British Royal Family?
I don't know if she's named for Queen Maud but Lord Frederick Windsor's older daughter is named Maud.
Here is a quote from Lord Frederick Windsor on naming his daughter, Maud.
Her full name is Maud Elizabeth Daphne Marina Windsor. "We liked the idea of an old-fashioned English name and there are a couple of Princess Mauds in my father's family from a hundred years ago – one was the youngest daughter of Edward VII who ended up being Queen of Norway, and another a grand-daughter of Edward VII by his daughter Princess Louise,” Lord Frederick told Hello! in 2013. "It's also a beautiful, elegant name and it was always our first choice. Elizabeth is a tribute to the Queen, Daphne is Sophie's grandmother, who she was very close to and Marina is my paternal grandmother."https://www.townandcountr...eugenie-bridesmaid-facts/
