I am daughter of Graciela Vallejo Lora and her mother was Mercedes Lora Ottenwalder from Santiago de los Caballeros, Dom. Rep. and her father Jose de Jesus Vallejo. I am working on the family tree, but my deceased aunt Margarita Vallejo Lora de Paredes did write a book on the family history: Vallejo Lora. Hope this was of help.
