I have read in books that in the early years of the white man in this country, the mountain lion was called "tiger".
The Creek Indians belonged to the town of their mother--my greatgrandfather, Moty Tiger, belonged to his mother's town, Tuckabatchee--his father's town was Thlopthlocco. Moty's father's name was Tulsa Fixico and his mother's name was Louisa Canard (Kennard). In our family, the name of Tiger began with Moty and his siblings. The name Canard began when a Scotsman, Kinnaird, came to America and married into the Creek tribe. The name Kinnaird has been spelled eight different ways--Kinnaird, Kinnard, Kennard, Kenard, Kanard, Canard, etc.--I suppose according to how the person writing it down knew how to spell.
Tulsa married a second time to a woman, Chamela, who already had several children. Tulsa and Chamela then had a son, Lumyer, and three daughters, Fickhumkee (called Millie), Hunna (Hannah), and Sophia. They were all given the last name of Tiger.
In a newspaper article during Moty's time it was told that he was originally named Homv Tikv, which meant first to cross. He was named after an ancestor on the Kennard side who performed a brave deed. His name was later changed to Moty Tiger--Moty after Moty Kennard and "Tiger" perhaps because that is how "Tikv" sounded or who knows.
A biographical sketch written about him said that he was the third son of Tulsa Fixico; however, I've never learned who the first two brothers were or how long they lived.
One Tiger family told us that they got their name when the children were lined up in school and said "hereafter your name is ______ and your name is ___________.
Also when Indians were enrolled the Indian names were written down according to how the person writing it knew how to spell or how it sounded to them. For example, there were two related families with the same Indian name and one ended up having their name spelled Ireland and the other one Island.
In addition to their towns, the Creeks also had clan names. One clan name was Tiger. Moty Tiger married Hettie Tiger and her clan was Alligator so my grandfather, George Washington Tiger, was from the Alligator clan, the same as his mother. George's second wife, my grandmother, was Susan Hampton. Her mother was a full-blood Creek Indian woman named Susie Nitie. She died when Susan was around a week old and her father died when she was 7 or 9. Judge Napoleon Bonapart Moore was her guardian and he sent her away to school so she never learned much about her mother. Therefore, I do not know her clan name.
So you can see the name could have started several ways for different families.
