80 to 100 years ago, many young people were sent to "Indian School" mixing many tribes. There were marriages that came out of that contact. I have a very good friend in Cherokee NC, whose name is Amy Grant Walker.
The Grant name came from her father who was Lakota Sioux, who met her mother a Cherokee in Indian School, not sure which school, but they married and he moved to the Tsali/Cherokee boundary. One of his sons is named General Grant. He is a very well know Artist and some of you may have met him on the east coast at Pow Wow's where he usually has a booth. Amy and General's father taught them the Lakota way, and their mother taught them the Cheokee ways. Amy is Pianist at a Methodist Church, but still leads Sweat Lodge prayer meeting on their parents property. I have been to their mothers home many times after a sweat, where Amy's son now lives. General Grant lives near by and has his art studio across the road.
There was lots of blending of Nations in the early and middle 1900's. I have a friend in Fallon Nevada who is Scotish and Ojibway married and living on his wife's White River Revervation there near Fallon NV. She is Shoshone. He is also a well know artist, and makes pipestone pipes. And other wonderful carvings. His name is Adam Fortunate Eagle. His Shoshone wife is Bobbie. Their son Adz, married Verna, a Navajo woman, who is is nurse named Verna.
The son and Verna are no longer married, but I am still friends with both families.
My mother is of Scot Irish and Scot heritage with a smattering of German and Cherokee and English/Wales. My paternal grandfather Gardner was about 1/4 to 1/3 Indian, the direct name coming down from the Catawba, either the Brown or Hagler family, but changed to Gardner in the later 1700's. His part German/part Cherokee Mother was Mary Helton, descending from the Hite/Christman/Helton/ Belk family from VA/TN/NC and Maries and Miller Co MO. The Cherokee ggggm came from Lee Co VA before coming to central Missouri.
My maternal Grandmother was Scot Irish, and Ulster Irish, from Co Tyrone and Co Donegal arriving in the late 1700's and the last one was Caldwell Maxwell, arriving in 1848. They all lived in York Co SC, but I have not documented any marriages with the Catawba. Most of the Catawba intermarriages were from early to middle 1700's The names Brown, Blue, Hagler, Ayers were a few Catawba that intermarried or took white English/Scot Irish/German names.
Some of my maternal grandmother's ancestor were also part German, and Indian. A Maxwell married a Barnhart of Greene Co TN to Maries and Gasconade Co of Mo. The Barnhart name has traced some Indian heritage, but they came to Missouri very early in the 1800's prior to roll taking and the trail of tears from NC, TN and GA. (mostly from Ga and TN), the TN counties that were Cherokee territory include McMinn, Roane and Monroe. Some of the old maps show the boundary.
What does that make me? I am 1/32 oe 1/16 mixed Indian heritage, Mostly Scottish and Scot Irish and Irish, with a smattering of Welsh and Alsace Lorraine German. A true Heinz 57 and proud of all my heritage.
