Abram and his brother Zeb are living in Hartford, CT on the 1900 censushttp://search.ancestry.com/cgi-bin/sse.dll?indiv=1&rank=...
Abraham Deveneu died January 9 1905 in Westfield, MA at the age of 92. His death certificate lists his mother as Rosella Fontaine.
Lucy "Devenew" died in Feb 26 1880 in Southwick, MA Her parents are listed as Joseph and Lucy Devenue (???)
I'm still looking for additional information.
PS if you send me a message through ancestry with your email address, I'll be glad to download those death records and send them to you.
