Tesshin Hamada, sensei lineage?

Could anyone here provide any info about the lineage of the Old Dominion University aikido program? My web research has turned up numerous references to the Dai Nippon Butoku Kai, but these are all in reference to organizational titles, and not lineage.
I came across info about Minoro Hirai, founder of Korindo Aikido, and his relationship to the DNBK, (as well as his cloudy relationship to Ueshiba) but again, no mention of lineage in the art.
Hamada sensei is said to be 24th generation samurai. Has anyone here trained under him and know who his teachers were?

If my memory serves me correctly, he is from Kyoto and learned from his father. He takes a serious approach to the art.

I would like to hear/read of any information you may have about Minoro Hirai, especially if is new and not part of the interview from AJ.

Thanks
