Who is the mystery lady?

The whole family was over having fun, when my uncle lets this lady in. The lady had told him that she needed to go in and talk to somebody. We all got quiet and looked at one another and said who's baby mother is this. She also had 2 girl babies with her. She set one on top of the tv and put the other one in her lap , sat at the kitchen table and started combing the baby's hair with a fork. She was smiling and humming. All my male cousins denied. She looked at each on of them then shook her head no.
