Do you have a source that supports that statement?

Y-DNA. Geg Albanians are mostly E-V13 (about 44%, haplogroup E about 46%) and J2 (about 17-18%), total E-J: about 65%.
Anatolian/Armenian haplotype R1b-ht35 convincingly covers Albanian R1b, is considered to just under one-fifth Geg Albanians has this haplotype.
