The Central School in Tierp said Anna Eriksson, 105, received one of the letters that were sent to more than 60 local children who were born in 2007, The Local.se reported Thursday.
Marinna Eriksson, principal of the school, said the population registry provided the school with the names and addresses of the children, and no one noticed one of the letters was being sent to Anna Eriksson, who was born in 1907.
"Her daughter got in touch and she and I both thought it was pretty funny. The two of them and I could see the humor in what happened," the principal said.
The principal said the senior citizen is still welcome to attend a school open house for prospective students.
"It would be fun if Anna Eriksson wanted to come here to meet the school's leadership and have coffee," she said.
