I thought by gypsy she meant traveling wanderers. I can't find it now.
Yes, that's what gypsies are.
'Gypsy' is a pejorative term for the Roma people, who likely came from Indo-Asia through Central Europe during the Middle Ages. Much like the Jews and other groups that did not have a land to call their own, they were universally reviled and hated. They still are; the Roma are alive and well in Europe, and there is still a lot of animosity and racism aimed at them.
It's a part of human nature that's been repeated over history many times; people who have no homeland, no knowledge of their place of origin are reviled. It's lessened since modern transportation means people can easily and quickly be displaced far from their homes. Even in America up through the 19th century there were the Pavees (called Travelers), mostly Irish immigrants who lived as nomads, and were hated for it.
Ever since we moved from our hunter-gatherer roots to agriculture, nomadism has been frowned upon, essentially.
So having a version of the Roma, or Jews, or Pavees, or any other group that live as nomads in the Middle Ages, but not have them feared and reviled for what they are with no explanation why that is, is hard on the suspension of disbelief.
