Good question as far as Edwin Lonsdale goes Ill have to pick up all my papers from my sons house to confirm. But now i can only say this much he was around Henry Dreers place and he has a few plants named after him. Mainly sports from Begonias, Should be a very old name have to look deeper on this one I welcome the challenge.
Here is my plant that I got as Buddy. It was planted in too deep of shade and the leaves stayed mostly green and were not remarkable. It was moved at the beginning of March to a sunnier aspect. It seems to be responding well to it's new location.
