I have a few! My dad is a natural redhead and I grew up being deeply jealous of not inheriting the same gene myself lmao I only have a reddish hue so I really like to give red hair to my characters, most of which are sadly missing from TH atm. But here is Edmund, who has the combo of freckles and red hair.
I also have Daniel, Karen and Merrill, and also arguably Knut (reddish hue) and Bambi (strawberry blond, which is honestly v close)
