I don't know if there is any relation, but I have found information of a Native American that went by a similar name. The article below is flawed, in that there are other articles claiming the same person was actually Native American and was enslaved at a very young age, raised with an African slave foster-mother, escaped out while still quite young, etc.
EARLY BOSTON MORMONS AND MISSIONARIES, J TO Z 1831-1860
Warner "William" McCary, alias Okah Tubbee pg 110.
McCary was an escaped Natchez, Mississippi slave who married Lucile Ann Celesta Stanton (daughter of LDS stake president Daniel Stanton) in 1846 in Nauvoo. McCary was ordained an Elder about February 1846 by Orson Hyde in Nauvoo. He and his white LDS wife pretended to be American Indians: he was a "Choctaw" warrior named Okah Tubbee and Lucile was "Mohican" named Laah Ciel Manatoi. Dressed in Indian attire, he would sing and play various musical instruments (most notably a "tomahawk" turned into a flute) and who eould give temperance lectures. After performing all over the west in 1846, they came east to perform all over the eatern seaboard, including Boston.

The article goes on to list advertisements that say that Okah Tubbee and his wife performed for the president, etc., raised thousands of dollars to aid the tribe or tribes. What the article, above, doesn't say is that Okah Tubbee went on to marry again, to Sarah Marlett of Syracuse, NY, while still married to his first wife. Bigamy charges ensued, along with a number of mocking and scathing articles directed either at Okah Tubbee or his foolish, young, romantic second bride.
