Do you think I should go ahead and marry her step sister 9 years after dating her and how should I go about it?

Should I inform the lady I dated in the past out of respect for her cos she will still eventually get to know?

Should I tell the lady I am planning to marry about the past relationship with her step sister?

As the topic states, I am close friends with a polygamous family of 2 wives.
About 9 years ago while a youth corper I dated the first born of the 2nd wife but we kept it secret, although I think her own mom knew although the mom is late now.

It wasn't a relationship per se as I was just sleeping with her and I knew she had other guys too at the time but she always wanted me to think we were in some sort of relationship just like most ladies would.
Anyway, the whole thing fizzled out when I relocated from that city.

8 years later, I am in a new city and meet her step sister, who is younger than her but from the first wife and we are getting along fine, turns out I really like her and now considering marrying her.

The lady I dated previously is currently not married, in her 30s and I heard she lost a pregnancy recently, I dont have any relation with her other than the fact she calls me occasionally to ask for money for assistance which I render when I have the means but sometimes I don't as I am also trying to put my life together.

I recall that she could be diabolic and wouldn't put it past her to do jazz or something.

Common sense should have told you not to have anything to do with 2 sisters from the same family, stop creating unnecessary avoidable problems for yourself.
