I don't know Rebecca's parents. I know her name was Rebecca Kathrine Pebbles who was married in Grafton, Haverhill, New Hampshire to Abiel Sweet Reed on Mar 1, 1847. She was on the 1860 New Hampshire Grafton Lisbon Census as 31 years old so she should have been born about 1822. She is the last person I have on this line.
Thank you for responding to my query.
Sincerely,
Kathryne Newcomb
