The main character, Jennifer? Jennie? Jenny? Possibly on the farm could’ve been the first.
These were a series of chapter books featuring an American girl who (moves?) to the country, detailing her charming life on a farm. There were several from when she was about 6-8 to almost 20 I believe. There were animal characters, a boy she might have married, various family members. She takes up ballet in later books. She wears her hair in looped braids. I read these as a child in the 80’s but they were clearly written much earlier. I would say 40’s or 50’s. Possibly 30’s or 60’s but doubtful.
I would so very much love to find them for my own daughter! I adored these- not only because she had the same name as me. I remember being even fonder of them than the Betsy Tacy books. In a way they were in between those and the Little House stories. Set the stage for Anne of Green Gables. So curious to know why they’ve disappeared!
