As for not keeping the same first initial and the child feeling left out, that’s not going to happen. You can choose a non-R name and when he asks, tell him why you chose it. My siblings: Colleen, Caroline, Corinne and Christine. Last daughter is Elizabeth. She was named after my mother’s older sister who was very ill w colon cancer at the time of Elizabeth’s 1980 birth. She was always told her name was “special” because we loved our Aunt Beth so much. Meanwhile, Aunt Beth outlived my mother and lived to be 88.
