I just started researching my family roots. My grandfather was baptized at st Eugene's in 1887. Address of 12 rock. londonderry, ire. His older brother was baptized at st Eugene's in 1879. His address was posted as Harvey street. I can find Harvey street but not rock. I was hoping to figure out a school that they possibly attended. Maybe there were other siblings. None of the census show the family. Any thoughts out there?
