Evachevski, Jennifer
From Spearfish Lake Tales Wiki
Jennifer Evachevski aka Jenny Easton (but NOT in Spearfish Lake), later Mrs Walworth. She is the eldest daughter of Gil and Carrie Evachevski (Matson) and was born in Germany, probably 1961. She has 4 siblings Garth, Brandy, Dan and Tara (full family tree here Evachevski).
She is a recurring character, even if only briefly mentioned in some books. Her first prominent role is in Busted Axle Road, where we also first meet her future husband Blake Walworth. The pair don't get married until Facing the Storm and subsequently have a boy, Jeremy. They live on the nice side of Point Drive.
She can sing a bit (see Jenny Easton). Blake teaches her to play guitar and compose music.
