Thank you Dede. I will see what I can find out about Omar, as well as Marcus, and look forward to receiving the extra details. It certainly sounds a sorry tale.
George's family also ended up in disarray, with the two boys in and out of military prisons, and his second wife and family in poverty and estranged from him, presumably over his failure to return from Bermuda, or to send money or letters.
The problem was that he was dismissed from his position with the convict service after a year and a half, and never made it back to England. Whether he had a break-down, was too penniless to afford the voyage, or just wanted to spend his last days in the sun I don't know! Half of the family even changed their name shortly after George's death in 1869. Having had an exemplary army career and provided the best he could for his family under trying circumstances I think George's story deserves to be told too, just like Marcus's.
I'll have some time at the National Archives in Kew later this year and hope to get more information about the 4LD then. It really is intriguing what happened to them all after their military service. And how events impacted on their families down through the generations. You're welcome to send directly to my e-mail address if you wish.
