h17

Analysis by 23andme identified my maternal haplogroup as H1 and my son's as H17. Their explanation is that his analysis is more detailed than mine, not inconsistent. Looking at phylotree, that doesn't make sense to me. H17 is a completely different subclade, not a "child" of H1. If it's that...

MTDNA confirms H17 but as I search for information about it precious little is available. It appears in Central Europe but our family history is a bit murky. Has anyone any advice on how to further search for H17? Thank you in advance.
