Our Gang Search-Please Help

[prccaap]

If anyone could please help me, I am looking to see which shows my grandfather was in. He would probably be in the episodes from 1925-1930 as an extra only. He was a little curly haired blonde boy named Robert Caldwell. He just died and his memorial service is on Sunday, so I need to know which episodes he was in, and which year. Thank you very much.

I am not familiar with the name. Here is a link to a site with good descriptions of the known cast, as well as the unknown extras.
