If anyone has any idea what font this is, please let me know. Thank you!

I don't recognize this one. If you could accept a substitute Google the words: fonts morris initials, and go to the images tab.

Thank you Don, I tried, but alas, no luck. Can you tell me the significance of 'morris'?

Late 19th century book designer, type designer and fontographer who revived medieval designs and was a major influence on the style of published books. His fonts are a fusion of Blackletter and Roman. His books used very ornate designs often involving vines and leaves. Your _O_ is a comfortable companion to his designs.
