ampacity?
(OP)
In a residence, can I use #6thhn, (copper) to feed from a 70a 2pole breaker in the main breaker panel to feed to a small subfed panel, or do I need to use #6thhn. Also, do I have to size the wire for the breaker being fed from, or for the rating of the sub-fed panel (125a)? Thanks!!

For sizing conductor's overcurrent protection look up Article 240 and also the ones related to panelboards. (Search for panelboards and switchboards in NEC).

What is the length of the cable? Voltage drop could be an issue with long lines (although in this case it sounds like you are ok). Also will this be run in conduit?

If it is broken, fix it. If it isn't broken, I'll soon fix that.
