What does the Polish feminine name Leskadia mean?
This *must* be the misspelling of Leokadia.
From the Greek Leokades. However, I found two varying meanings/derivations:
1. from the words leos-people, and kados-care.
2. leukas - light, clear
Its about the 130th most frequent among the Polish population today.
It's familiar, but *very* old-fashioned, not in a good way. Nicknames Loda, Lodzia (pr. Lodzha). There was a St. Leocadia of Toledo in the 3rd century, a martyr.
Sincerely,
