Aloha everyone,At long last I have finally found some proof of Henry Austin Pineo in the 1850 Federal Census for Massachusetts, residing in Ward 11 of Boston under the name of PINES (not Pineo).You can see the family on lines 17-21.The census was enumerated on 21 Sep 1850.
Henry A. Pines, 48, Carpenter, b. Nova Scotia Jemima ", 39, b. Nova Scotia Olive I. ", 66, b. Massachusetts Susan ", 8, b. Massachusetts (school within the year) Abigail ", 6, b. Massachusetts (school within the year)
The Olive I. Pines, seems to be his mother, Olive Comstock.This is the first time I have seen the initial "I" for her.
Susan is Susan Elizabeth Pineo Abigail is Abigail La Havre Pineo (never married, in later years she is also found in other census under Pines & Pineo, usually residing with Bates families in Cohasset).
I believe Henry's middle name of Austin was named after or in memory of his uncle Austin Pineo who was believed lost a sea.
If anyone doesn't have access to the census on-line, just drop me a line and I'll be glad to forward you a copy of the image for your research.
