Looking for the Family of Ann Fogary Dob 25th July 1940 Had 6 Siblings IN Ireland

I was adopted as a baby. My Mother was Ann Fogarty (now deceased) who was born on 25th July 1940. Her Mother was called Mary. Married to a 'jockey' who died when Ann was 9 months old. Ann was one of 6 siblings. Left in a Catholic orphanage in Ireland at a young age with her siblings,as a results of her Father's death and her Mother's mental health after death of her husband . Looking for all my Aunts, Uncles and Cousins. Have made contact with my half brother Christopher. Any help would be greatly apprecaited.
Thank you
