Kathleen is the early Irish import version that came between Katherine and Kaitlin, and which hasn't been used in so long it's almost beginning to sound fresh again. It was a surprise pick by one of the hip Dixie Chicks, Martie Maguire. Kathleen was a Top 10 name from 1948 to 1951, and it is the subject of several old sentimental songs, such as "I'll Take You Home Again, Kathleen."

Maude, also spelled Maud, is a lacy, mauve-tinted name that was wildly popular a hundred years ago, but has been rarely heard in the past fifty. Some stylish parents are starting to choose it again, especially as a middle. 
 
Maude's early popularity was influenced by the Tennyson poem that included the oft-quoted line, "Come into the garden, Maude." Then, in the 1970s, along came the sitcom Maude, featuring the vociferous and opinionated character Maude Finlay, putting a very different spin on the name. But enough decades have now passed for the name to have settled back into its soft, sweet pastel image.
 
Parents today are more likely to associate the name with young actress Maude Apatow, who rose to fame in HBO's Euphoria. She may be the catalyst needed to finally popularize her name again.
 
The Maud spelling has British royal associations via the daughter of Edward VII, who later became Queen of Norway; Maud Gonne was a famous Irish political activist.

Vice President Aaron Burr named a daughter Theodosia ("Dear Theodosia" is a song in the smash musical Hamilton), and it was the birth name of silent screen vamp Theda Bara. Theodosia actually appeared on the US popularity lists in the 1880s and 90s.
