We have great news for Mallo-Mallow family researchers - on both sides of the Atlantic this time.
The yDNA test results are back for a descendant of Peter Mallo who immigrated to Pennsylvania circa 1792.The 12 marker results are identical within the statistical allowance (a variance of 1 on 1 marker) to the yDNA results for three lines of male descent from Michael Mallow (aka Mallo) b. 1720 Griesbach d. 1772 Virginia (now WV).The common male ancestor is an earlier Michael Mallo b. ca 1643 d. 1735 Griesbach.
Twelve marker results are best used to determine if further testing is desirable.However, the family's well-documented genealogy, both in the US and back through several generations in Europe, combined with the uncommon surname as well as the relatively uncommon haplogroup, put us on the fast track to having a base-line yDNA profile for the male lineal descendants of Michael Mallo b. circa 1643.
Test results for 3 of the 4 descendants can be viewed here:
Top line is from the descendant of Peter Mallo who immigrated ca 1792 to PA. Second line is from the descendant of Michael Mallow Jr (1762-1830 d. Allegheny Co, VA) son of Michael Mallo the immigrant (1720-1772). Third line is a full 67 marker panel from a descendant of Henry Mallow (1758-1834 d. Pendleton Co, now WV) also a son of Michael Mallo the immigrant (1720-1772).
Further testing of additional descendants is expected to confirm these results.For practical purposes, we'd expect other lines of descent to match these results within the allowances. That means other lines of male lineal descent in the US which includes descendants of George Mallow of Peaked Mountain (Rockingham Co., Virginia) and Adam Mallow (who moved to Ohio from now WV in the early 1800's) - and the same for the other European lines of descent from Michael Mallo b. 1643.
