Kieran spoke to a lot of Native Americans on his visits and most knew of a European ancestry which could explain their red hair.

“The thing that surprised me was how early on there were these Scots and Irish marrying Native Americans,” he said.

Lottie Wahkinney, a Comanche girl from Oklahoma, has Scottish grandparents, from Hawick.

Her father Jared told Kieran his dad was Comanche but his mum was born and raised in Scotland.

“That’s why my Lottie has a good mix of everything going on,” Jared said.

“My Scottish grandparents would come over every summer.

“On my first visit to Scotland when I was 22, folks were like, ‘Where are your moccasins? Where’s your headdress?’.

“I explained ‘I wear Nikes’.”
