I am a descended of Ambros Warren.
My Mom grew up in Chapel Arm. Her parents were Albert Warren & Marion Rowe. She went home resently for her brother's (Roy Warren) funeral. She brought to back to Texas a book on Chapel Arm from 1838 to 1998. It has a lot of info on the town & people. There is also a web site on Chapel Arm. This has helped in researching her family.
I don't know/have any information on the Power family in Waterford. I have been mainly researching the Fogarty & Barron families. I have been trying to find how my GGGrandfather left Ireland and what happen to his brothers & sisters. If I see anything that will be of use to you while I am researching mine, I will let you know. Also try the Waterford Heritage Center, they have help me.
If you need anything on Chapel Arm Newfoundland, send me a email at fog2432@lcc.net and I will try to help.
If you could write (email) and tell me a little about you or your family would be nice.I will tell you more on mine. My mom will be very pleased and curious that I have communicated with some one from her home town.
