I want to know the names of some of Martha's male family/ancestors, but all I've managed to find out so far is that her father was called William. All the other info I've found relates to the Kent side of the family. Does anyone know of any other names belonging to the Clark family from any Superman media or fanfic? Or have I come across a fairly blank slate?

This site lists a "Bertram Clark (uncle, deceased)" as Clark's relative. This is the only reference I found about a male from Martha's family.

Thanks! At least I've got a couple of names now: William and Bertram. Still happy to add to the list if anyone knows of any others.
