I was cleaning up his bio and cross checking Findagrave, when I came across a little mystery. Francesco Joseph “Frank” Capra (1887-1943) is linked there as the son of W. B. Yeats and Retina DeSalvo Capra. Frank was born in San Polo Matese, Italy, at a time when Yeats would be 22 and she would be 20. However, the Wikipedia page has him living in Ireland at that time and moving to London in that year. There is no mention of a side trip to Italy.
I found an article that says she was first married in 1891, in Duluth, but makes no mention of the connection.
I've suggested that the link be removed.
For those interested, the line traces down to Norman J Mastrian, who was convicted of first-degree murder.
