These appear to be Bohemian beads from the late-19th/early-20th centuries.

They would be related to what are popularly called "Russian beads."

Although it is believed by some that glass beads were made at Jamestown, this does not appear to be a true story. As I understand it, they brought over an Italian glassmaker. But he (may have) proceeded to become a drunkard, and never produced much of anything.

The beads that would have gone to Jmestown at that time would mostly be plain drawn beads (perhaps dark blue, and perhaps other colors); and a-speo rounded glass beads of the "gooseberry" and similar types.

These are very different from the beads you show.
