looking for Brother and sisters

My birth mother was Mary Alice Ricks she had a son born between April-July 1961 in Dallas Texas at Home for unwed mothers. I believe his name was Gary. After I was born she left my brother and I around 1964 she had Hollie Walker that was put up for adoption who resided in New Mexico last I heard from her and April Massey who I know nothing about except she was married to Louie Massey when Hollie and April was adopted out. My mother Mary passed a few years back in Mississippi living with one of my half sisters Michelle. I just recently found out she had 2 brothers who had been separated from her and each other and have met one on the phone and facebook. I would love to get to know my siblings and so would my brother and sisters. There are 7 of us all together
