This is a Set of 6 Handled Mugs(possibly Child's Mugs or Cups) that have Lutes with Garlands and a Bird on a Nest. This Pattern of Early American Pattern Glass is attributed to McKee Glass, Cica 1880's.
I would think that these are hard to find in a Group, I dug them out of a Box in my basement where they have been stored for many years. Some on them have gotten that pale lavender tint.
They measure 3 1/4" high x 3 1/8" across the tops and 4" across with handle. A couple have roughness at top edge, 1 has a small chip under edge; but pretty good for Antique utilitarian glass.
