On May 24 2022, Sumrin Saint Mary was covered by Sumrin Topelius for a 2023 foal.
On April 15, 2023, she gave birth to a chestnut (will turn grey) filly named Sumrin Sylvia. One of the most famous works of the writer Zachris Topelius is "Sylvia's Songs", so the name is a tribute to her sire.
Unfortunately, Sylvia broke her leg in the field, an operation could not save her anymore and she passed on May 1st, 2023
