Hi Marylin,
All three words are Ashkenazi Jewish names from Eastern Europe. Leiser (Leizer, Lazar) is a shortened form of the Hebrew name Eliezer. Cerne (Czerne Czarna) is a name of Slavic origin meaning Black. Examples of using this form are: The renown Russian-born Hebrew poet Tchernichovski, the Infamous nuclear plant at Chernobyl, Czarnogora (Black Mountain) the local name of Montenegro and so on. Breine / Breina is the female Slavic name derived from Braun (German) translating to Brown.
A good reference book for the meaning and origin of Jewish names is "Jewish Family Names and Their Origins" by Heinrich and Eva Guggenheimer.
