No connection at all.
My wife has a Harpers Ferry Maynard that was assembled from parts left over from the original company. While it's not up to the quality of an original I see nothing wrong with it. I have a Charleyville that I bought as a "kit" which also came from left over inventory. A 2 piece walnut stock and a Numrich shotgun barrel which, I understand, has a very long breech piece fitted to make it the correct length. The lock required a lot of work to be acceptable. I have never seen a HF 61 or 63 and I've been skirmishing for 40 years. All of the parts left over were sold off long ago.
"One of the owners" had somewhat questionable moral standards and received a free vacation at a Federal hotel on charges unrelated to firearms. All of the firearms assembled by HF or others after were assembled from legally obtained inventory so there is no issue there.
