I would suggest contacting all descendants of your great-grandfather. If that yields nothing, ask descendants of brothers or sisters or Mr. Gamman. If that doesn't work either, try looking into his wife's family. They may have taken a photograph of him with your great-grandmother.

Thank you I have tried the larger family. I did find one online under marriages.
