I realize this message is a few years after your posting, but I believe my Chaffee Family Bible has a lot of useful information. It lists a Lucy Adeline Chaffee, born 5/13/1808, a sister of my great-gandfather, Rev. Francis Marion Chaffee. She married James Cady Chaffe, who was born 2/22/1804. There were, indeed, 11 children born to them: James Franklin C., Ambrose Leucrates C., William Charles C., Francis Marion C., Ruby Adaline C., William Severson C., Meary Alzina C., Albertus Bellnap C., Catharine Jane C., Rachel Mariah C., and Caroline Amelia C., the last born in 1847. I hope this helps.
