Genetic Research Results:
As of April 2011, 37-Marker Y-DNA kits from members of four different surname variations : GAVANESCH, GAVENESCH, GABENISCH, and GABENNESCH have been returned with excellent results.
Each member is in the Haplogroup E1b1a8a with origins from Sub-Saharan Africa. According to Chris Rottensteiner, Administrator of the FTDNA Alpine Genetics Project: "I have linked all projects with ties to Alpine origin as I think it is interesting. Your haplotype seems very seldom in Europe and so far I know no connection to your Gavanesche E1b⇾U175⇾P278.1⇾L609+ cluster." http://alp.gen.or.at/
The GAVANESCH, GAVENESCH, GABENISCH, and GABENNESCH Project Members had test results with a genetic distance of no more than 5 from another Project Member on the 37 Y-chromosome STR marker test:
One mismatch (genetic distance of one), at DYS570 between the GAVANESCH Project member and the GAVENESCH Project member demonstrates a 97.21% chance that they shared a common ancester in the last 12 generations.
Two mismatches (genetic distance of two), at DYS576 and CDYa between the GAVENESCH Project member and the GABENNESCH Project member demonstrates a 96.35% chance that they shared a common ancestor in the last 16 generations.
Three mismatches (genetic distance of three), at DYS570, DYS576 and CDYa between the GAVANESCH Project member and the GABENNESCH Project member demonstrates a 95.85% chance that they shared a common ancestor in the last 20 generations.
Two mismatches (genetic distance of two), at DYS439 and DYS448 between the GABENNESCH Project member and the GABENISCH Project member demonstrates a 97.6% chance that they shared a common ancestor in the last 16 generations.
Four mismatches (genetic distance of four), at DYS 576, CDYa, DYS439, and DYS448, between the GAVENESCH Project member and the GABENISCH Project member demonstrates a 96.44% chance that they shared a common ancestor in the last 24 generations.
Five mismatches (genetic distance of five), at DYS570, DYS576, CDYa, DYS439, and DYS448 between the GAVANESCH Project member and the GABENISCH Project member demonstrates a 90.22% chance that they shared a common ancestor in the last 24 generations.
This Most Likely Estimate (MLE) of a maximum genetic distance of 24 generations (approximately 600 years) coincides with the conventional genealogical research indicating that the Most Recent Common Ancestors (MRCA's) were born sometime in the early 1400's or before.
