Ashley Marin is Big A? Maybe there's no twin-theory, maybe there is triplets?

Hi everyone!
Today i make a few new posts here and my first is theory about Asley Marin of being big A.
That parent has always been some kind of mysterious. I don't know why, but for me, she is.

So i start this theory about that i watched PLL series cast at imbd.com and there is numbers how many episode the character has been. And Laura Leighton (Ashley Marin) has been in every episode. Even tho i haven't seen her in every ep, expect if she's A, then there is a possibility.

So, what could be Ashley's motive?
I think that she is connected to Bethany Young somehow. I've thinking that what if there is no twin-theory, but what if there is triplets? 
Could those triplets be Hanna, Bethany and the sister which Bethany killed.

Also, Ashley is the only one who has seen that weird blond child (Bethany or her sister) in the halloween. And Hanna saw twins in Ravenswood? Hmm.. why are those twins connected to Marin's family?

Well, what is Jessica D. implication in this whole thing? Maybe she knew Marin's family secret, and that Bethany killed her sister, and exposed her to police. Ashley and Jessica D. were friends, so they might have known their secrets?
Jessica D. was always mean to Hanna also. Why is that? 

In first season of pll we also saw some Ashley's true nature, that she is ready to do anything for her daughter. And she will crush anyone who tries to hurt Hanna. That could be motive too. --> And she did slept with police, she ran over Wilden with a car, she stole money (A have lots of money) and Mrs. Potter (owner of the money) died suddenly. 

Hanna was best friends with Mona, and Mona was many times in Marin's home. That how Ashley could have been close to Mona (first A)

Why Mona said in Radley to Hanna that she can't trust even her own family?

Some clues

- A likes alcohol, Ashley likes too.
- Ashley has a silver laptop, A has too.
- She fits also perfectly in Black widow's costume.

Many of you may think why Ashley would do such a horrible things to her own daughter, if she's A. Maybe she does because she wants that nobody will not suspecting Hanna or her.

And one thing what came in mind is that, when i post that imbd-thing to Facebook, in pll community, suddenly i didn't find my post there anymore.
