I first made this for my fiance and it turned out so good that he raves that it is the best split pea soup he has ever had. I made this remembering what my grandmother used to do after Christmas every year.
In a large stock pot, cover peas with 2 qts cold water and soak overnight. If you need a faster method, simmer the peas gently for 2 minutes, and then soak for 1 hour. (Some dried split pea packages from the store do not need to be soaked before cooking)

Once peas are soaked, add ham bone, onion, salt, pepper and marjoram. Do not add any more salt or pepper until the end to make sure it is to your taste. Cover, bring to boil and then simmer for 1 1/2 hours, stirring occasionally.

Remove bone; cut off meat, dice and return meat to soup. Add in the chopped ham, bacon and turkey meats. Add celery, carrots and potatoes. Cook slowly, uncovered for 30 to 45 minutes, or until vegetables are tender. (At this point add more salt or pepper to taste if wanted.)
