WHERE WERE MY ANCESTORS 150 YEARS AGO?

Here's last week's Saturday Night Genealogy Fun challenge from Randy Seaver at Genea-Musings:

Your mission, should you decide to accept it (cue the Mission Impossible! music) is to:

1)  Determine where your ancestral families were on 25 June 1866 - 150 years ago.
2)  List your ancestors, their family members, their birth and death years, and their residence location (as close as possible).  Do you have a photograph of their residence from about that time, and does the residence still exist?
3)  Tell us all about it in your own blog post, in a comment to this post, or in a Facebook Status or Google+ Stream post.

On my Mom's side of the family, most of my ancestors were still living in Ireland,
Scotland, or Germany, and I have no record of where they were or might have been
in 1866. I haven't found much yet on my 2x great grandparents who were in this country, Patrick J White (1848- 1902) & Mary (Powers) White (1848-?) and their parents.
Part of the problem is the commonality of the Irish family names in a period when Massachusetts was seeing a great influx of Irish immigrants.

Even on my Dad's side with all his family living in Maine and New Hampshire
there are a few missing a date of death, so I don't know if they were even alive
in 1866. In those cases I've left their names off this post.

Anyway, here's what information I was able to find on the paternal side of my
family:

My 2x great grandparents Asa F Ellingwood (1828-1921) and Florilla (Dunham) Ellingwood  (1832-1917)were living on a farm in Dummer, Coos, NH with their 8 children.. My 2x great grandmother Clara Ellingwood 1865-1901) was just 1 year old.

2x great grandfather Jonathan Phelps West (1834-1917) and his second wife Louisa A Richardson(1837-1925) were living on their farm in Upton, Me.

My 3x great grandmother Arvilla (Ames)West (1810-1907) was  a widow of 4 years, her husband John Cutter West having died in 1862. She was living on the farm in Upton, Me. with Jonathan and Louisa

My 2x great grandparents Nathaniel Barker(1794-1884) & Huldah (Hastings) Barker (1798-1884) were living  on a farm in Albany, Oxford, Me. My 3x great grandparents Nathaniel S. Barker(1830-1884) & Lucy (Coburn)Barker(1842-1904) were living with them. My great grandfather Frank W. Barker(1865-1905) was only 1 year old.

My 3x great grandparents Amos Hastings Barker (1828-1907) & Betsy J(Moore)Barker (1842-1924) were also living in Albany, Oxford, Me on another farm with their 6 children.

3x great grandmother Hannah (Upton)Moore Emery (1814-1896) was also living on a farm in Albany, Me with her second husband, Peter Emery.

3x great grandfather James Thomas Dunham(1805-1888) was in Greenwood, Me with his second wife, Polly Lowe.

3x great grandfather Wesley Coburn was a widower living in Albany, Maine.

That's all I know at present.
