Henry Boston - DNA

There is no DNA attached to his profile.
So far back there is no chance to see / confirm that you are related with DNA.

Anyhow, as a start you should build your tree here on Geni until you get duplicate profile hints that gives you a chance to get connected to the world tree where Henry is.

I would also recommend you to upload your DNA to FTDNA and from there link it to your Geni profile to get matches with other profiles.
