Last year I blogged about GEDmatch’s “Are your parents related” where it looks for Runs of Homozygosity or identical alleles on paired chromosome that would indicate a possible close relative.
But now that I have found & confirmed my mother’s biological parents, I took a look again at GEDmatch’s “Are your parents related” tool to see their predicted genetic distance.
It estimated 4.1 generations to the MRCA (most recent common ancestor). I normally do not go by GEDmatch’s predicted estimated number of generations but in this case because I cannot determine whether 51.5cM is a lot or not, and if 13.9cM largest segment plays a pivotal role or not, I am going by their estimated number of generations.
This is my mother’s genealogy. I italicized all females.
1) Mahi – Ko’olau, O’ahu
2) Kumahaulu – O’ahu
3) Kaapuiki – Kapa’ahu, Puna, Hawai’i
4) Piipii – Puna, Hawai’i
5) Naea – no information
6) Kamau – Hau’ula, O’ahu
7) Ehu – Mapulehu, Molokai
8) Kalahope -Pulama, Puna, Hawai’i
9) George – Kalapana, Puna, Hawai’i
10) Laahiwa – Kalapana, Puna, Hawai’i
11) Hookano – Honomuni, Molokai
These are my Kanaka or aboriginal Hawaiian ancestors. The people I specifically chose were at the end of my genealogy branches. I’ve listed their known origins with the names of the place (ahupua’a), district and/or island. The main thing to look for is that both of my mother’s parents Joseph and Rose just do not have families coming from the same areas.
My grandfather Joseph’s family was from the island of Hawai’i. Rose’s paternal grandfather John was from Molokai as well as his wife Hookano. Ehu was also from Molokai while Kamau was from O’ahu. It is not clear where John’s father Naea was actually from.
The point of all this is to show how contrary to predicted closeness with all of these DNA companies and even a tool to look for ROH, that there is still no known close connection to my grandparents.
