Lily Evans Potter relationship to Voldemort

This is my first post, so please forgive me if it is in the wrong 
place.

I've read much discussion about a possible relationship between V and 
Lily Potter, but something just hadn't seemed right, until it finally 
dawned on me what I was missing.   

Various theories include V wanted to save Lily as a prize for Snape 
(or someone else, maybe Pettigrew?) that he was some kind of blood 
relation to Lily, that they had been lovers at some point, or even 
that he was planning all along to kill the woman, but wanted her to 
step aside so he could kill her baby first.  I'm sure there have been 
other theories I haven't read.

Here is why I think there MUST be a blood relationship of some kind 
between Lily and Voldemort.  

Canon: When Voldemort went to kill Harry, he had just killed James.  
Lily knew he was there to kill Harry.  Voldemort told Lily to stand 
aside.  When she didn't obey him right away, he told her to stand 
aside *again.*  When she didn't stand aside after (at least) two 
warnings, he killed her, then tried to kill Harry.

Lily was Head Girl at Hogwarts, and was described by someone 
(McGonagall?) as being one of the finest witches of the age.  That 
may have been simply a comment on Lily's moral qualities, or it may 
have been a comment on her magical abilities.  Either way, she was no 
slouch as Head Girl.

As a loose comparison, think of Hermione -- not as a fourth year 
student but as a fully grown, powerful and accomplished witch -- 
being told to stand aside by someone who had just murdered her 
husband, so he could murder her child.   Would she just stand 
there?   Can you imagine what Hermione would *do* to someone in 
circumstances like that?   Just because V is powerful doesn't mean he 
is immune to attack.

That indicates that V had a strong reason for keeping Lily alive, 
because he was taking a very large chance in not killing her first.  
There has been a ton of speculation as to why he might want to spare 
Lily.

That's all been gone over before, though.   What just struck me is 
that from V's POV, V must have *trusted* that she wouldn't blast him, 
after watching him kill her husband and baby.  V is definitely 
maniacally obsessed with gaining power, but he is no fool.   There 
HAD to be a reason why he would trust that Lily wouldn't kill him.

I can think of only two explanations for V to reach that conclusion 
(that Lily wouldn't kill him).  One is that there is a blood 
relationship between them, and the other is that something else 
created a magical bond between them, that would make Lily most 
unlikely to kill V.  A previous romantic interest most certainly 
would *not* do it.

It's hard to imagine *anything* other than a blood relationship that 
would make V trust that he could murder a powerful witch's husband 
and son in front of her and live through it.  The closest one I can 
come up with is that Lily saved V's life at some point.   That would 
create that unbreakable magical bond between them, and would be why V 
didn't want to kill her -- and maybe even was why her sacrifice of 
her life for her son would give Harry the protection against avada 
kedavra from V.

While that makes sense from several different perspectives, I don't 
think that one is right, either, because it would show why V wouldn't 
want to kill Lily, but it wouldn't show why he would trust that Lily 
wouldn't kill him.  

That leaves a blood relationship as the most likely candidate I see.

Any other ideas?
