My whole life I was the only Elinor, & even more so the only Elinor spelled the (Welsh) way I do. Suddenly, Eleanor/Elenor/Elinore/even Elinor is a mini-trend. I know (of) quite a few under the age of 10.
"Eleanor has reach the top 10 most popular girls name 2 times, and has reached the top hundred names 67 times. Eleanor has been used in the United States ever since 1880, with over 298,124 girls given the name in the past 200 years," according to this site. There were only 4x as many Eleanors born in 2020 as the year I was born but I'm guessing it's a more popular East Coast name now than it was in South Dakota in the '50s. Which is why I seem to have run into so many.
