Where & who is Alicia ?

I had class tonight on child abuse from 6-9 p.m and suppose to do child abuse prevention on wed. from 6-9p.m when i get to class I'm told there is a schedule conflict. needless to say i had class until 8 p.m and got credit for 6 hrs.. when get home i check the messages , Jessica called so i call her back, and she proceeds to tell me that there is a girl named Alicia looking for her family , she believes we are that family. Alicia shares our grandmother Ruth, cousins, aunts and uncles.. although i don't know who she is.. Alicia thinks my cousin Micheal could be her father.. I'm not able to verify that. ( I 'm not aware the he has children ) So this got me thinking.. Could this be my Long lost sister ? Nikki and I did some research awhile ago and found out that we have a sister that was born between Nikki and Jessi whom was given up for adoption , she was conceived with another man ( not our father ) while my parents were married, Could we finally be getting closer to the truth ? So Alicia if you come across this PLEASE try to contact on of us, you could be my sister and we would love to find out !
