"Variant of Markellos"
The name Markella is commonly a female name from the "Greek" origin.
Markella is the Greek feminine form of Markellos, the Greek rendering of the Latin family name Marcellus, itself a diminutive of Marcus. The feminine ending -ella is the same one that gives Marcella in Latin and Italian. The name is also borne by Saint Markella of Chios, a figure in the Greek Orthodox Church.
The pronunciation of Markella is mar-KEL-uh.
