And when things are looking more solid make sure to update your ancestral surnames on FTDNA and add in your family tree as they are very useful for helping people figure out if they have any matches. If you haven't done so already you can also add your autosomal data to GEDmatch.
This is the extra bonus of pushing your family tree back a generation as you double the number of ancestral surnames as it feeds into your DNA tests (helping get more value out of them) which may then help with the family tree.
