Welcome to Rootschat kewyatt,
You'll find lots of friendly, helpful people here.
I had most likely ruled out the Robert Muir on the
Ganges Khan because of what fellow RCers had found, but I would love to know any information you have about your Robert, so I can confirm it's not him. I think mine most likely came on the
Malabar in 1853.
My Robert's parents were another Robert (1795-1873) and Jane McCunn (1802-1877). As far as I know, he didn't have a brother Alexander.
Cheers,
Alison
