Meaning
What does Tamsyn mean?
The name Tamsyn is an English variant of the Greek name Thomasina, which is the feminine form of Thomas, derived from the Aramaic name Ta'oma meaning "twin". It emerged in the Middle Ages and was particularly popular in medieval England and Scotland.
The earliest recorded use of the name Tamsyn dates back to the 13th century in Scotland, where it was spelled as "Tamsin" or "Tamsyne". It was a common name among the Scottish nobility and appears in various historical records and literary works from that period.
One notable historical figure with the name Tamsyn was Tamsyn Weircruke, a Scottish woman from the 16th century who was accused of witchcraft during the Scottish witch trials. She was tried and executed in 1597 in Edinburgh.
