I'm ready to continue Happy Tears.  I'm going to focus on Happi in his
twenties.  Can anyone help me with when he met up with Luckosai?

I understand the following:  (Understanding does not mean knowledge)

Tarou was given his name and curse approximately 20 years before manga
timeline.  

The "other" Tendo sisters were helped by Happosai between 10 and 15
years before appearance.  Anyone have a tighter timeline?

Hinako-Sensei was helped by Happosai approximately 14 to 18 years before
appearance in story.

Now comes the fun part, Am I correct?  Please, let me know privately at
the email address below.  That is my home account.  Please do not reply
to sender as I am using my work id to send this..  

Here is an extra bonus question:  Is there anyone else in the manga or
anime timelines that Happosai has a history with?  If so, who, what when
and where?

Thanks to everyone in advance,

P.S.  I will post the consensus answers when the responses die down.
