[Facts] Re: The name "Tweed"
From searching the birth indexes (which goes back to 1855) there doesn't appear to have been a single girl born in Scotland with the legal first name "Tweed" since at least 1855. Even as a middle name (it was very common in Scotland for people's middle names to be taken from meaningful surnames) it's incredibly uncommon - though there are about 30/40 instances. But there's also "Tweedie" which is about 10x as common as a middle name, and there have even been 3 girls with Tweedie as a first name:
One was born on New Year's Day 1901 and had the absolutely extraordinary first-middle name combination of "Tweedie Centurion". Her parents must have wanted everyone to know she was born on the first day of the new century! (Tweedie in this case I imagine is an elaboration of twenty)
Fast forward to 1913 and another girl named Tweedie is born. This time, her name comes from her mother's maiden name, which was Tweedie-Stodart. It was relatively common until the early 20th century for minor aristocratic families to preserve surnames this way, by passing it down as a first name to a son (or occassionally - as seen here - a daughter). From records on Ancestry I see that this Tweedie eventually emigrated away from Scotland - perhaps she could be the very person you're looking for information about!
The third Tweedie was born 100 years later - in 2023. With many surnames becoming popular first name, and diminutive names ending in "ie" being common, it's not too surprised to see this name being used again.
