Boy howdy, am I going to just mess this up – but here is a mt-DNA, slap it together in five minutes, I-got-my-results-now-what – moment.
The best place to start is Maciamo Hay’s website Eupedia – just google Eupedia and any haplogroup you like – add the qualifier of either mt-DNA or y-DNA and boom you will have the best explanation of the haplogroups you can find anywhere on Maciamo Hay’s wonderful website.
Here is Eupedia’s mt-DNA Haplogroup H page… (Look for your sub group – if your refined group is not listed then it is not written about yet and maybe you are refined to a rare spot – hooray!)
https://www.eupedia.com/europe/Haplogroup_H_mtDNA.shtml
So for instance – Hay’s Eupedia notes that MOTHER H1 lived about 22,500 years ago! Easy to read!
Then of course Rebecca’s Ab Fab site Haplogroup.org site and here is a note she has for H1a
https://haplogroup.org/mtdna/rsrs/l123456/l23456/l2346/l346/l34/l3/n/r/r0/hv/h/h1/h1a/
There are always Facebook groups you want to search for. Use the qualifier of wither mt-DNA or y-DNA and had yours and then search – there are groups for every aspect of DNA research.
There is even a group for our own H1a and H10 and H3 and so on.
Then of course the wonderful ISOGG –
https://isogg.org/wiki/Mitochondrial_DNA_haplogroup
and their tree!

From this page see – RO and that SHE was the MOTHER of H! Click on RO and see the DESCENDANT mutations.
{{this is for the y-dna (male line of a male) on ISOGG – }}}}
And the use of Helena for the mt-DNA Haplogroup H is from Bryan Sykes’, the British geneticist’s book

The names were updated – at one point and then the idea of using names was sort of dropped and now we are usually just the groups
I am H10a1, my hubby is H3k1a, my father’s mother’s mt-DNA is H1ag1
My daughter-in-law (and so grandchildren) is U3 and my other daughter-in-law is H59.
