Hi RoMay,
I would suggest, trying a "people search". Since the records of <living> persons, won't be public for another 100 years... it is likely, your best bet at finding her.
May I ask, what your relation is?
And I was wondering, if you possibly had a name on her grandparents? First name would even help, to narrow it down. As they are likely, no longer loving and there may be an obituary or some other lead, as to where their relatives might be residing.
Also, using the surnames search feature on Geni, for Lopez.. Yes there are many, but not all are named Alicia.
I did a people search, just to see the odds and there is actually, an Alicia Lopez as a user on geni, too... she has added a number of Lopez profiles, as well.
I am not a pro user though and therefore, am not able to just click on her profiles to locate her as manager and to follow her. But you should try to locate a Lopez profile of hers on the surnames search and then, add her, to your follow, list.
Etc. etc.
I would also, suggest, creating a user account on myHertitage and Ancestrt and using their message boards, to post this same request for information about her. The more places you post in, the larger the audience and you may just get lucky and someone who does know something, might see your posts.
I wish you the best of luck!
