Here's five photos I bought online that were sold as a group.

Names are written on the back of each picture, but most of the names were apparently misspelled.

After doing a little research I came to the conclusion that the first 3 photos here are members of the Pogue family.   More specifically, they are children of James William Center Pogue (1839-1907).

      J.W.C. Pogue was an important Tulare County pioneer.  He was a successful citrus grower,  rancher and businessman.  He also served two terms as a Tulare County supervisor, and he created the town of  Lemon Cove, CA.   The historic Lemon Cove Woman's Clubhouse was originally the Pogue Hotel, and then later the Pogue residence, before the family deeded the house to the Women's club.

Because this is a family of some importance it made it somewhat easier to identify these Pogue family members.

The last two pictures here are apparently members of the Moffett family, although I'm not exactly sure yet which of the Moffetts they are.     On two occasions there appears to have been intermarriage between the Pogue and Moffett families, and Eva Pogue (photo just below) co-wrote a history of the  "Blair - Moffett"  families.

At the bottom of this photo it says:  "Flaglor",  "Instantaneous Photographs", "S.E. cor. Market and Ninth Sts."', "San Francis."   (circa 1885-1890).      On the back is written:  "Eva Pogue".   I'm sure this is Sarah Eva Pogue (Later, Eva Pogue Kirkman). Born: Dry Creek, Tulare County (in 1870),  D.:  in 1946 (Exeter, CA).

 On the back of this picture someone has written: "Jene Pague".  I'm fairly certain that this is a photo of Nancy Eugenia Pogue  (later, Genie Pogue Crookshanks),  b. 1864, Venice Hills, Tulare County,  d. .1931, Exeter. CA .       The Photo is by: "Bell", "Santa Ana, Cal", (circa 1885-1890).
With both Genie and Eva Pogue it is possible to find other photographs of them on the internet, which helped considerably when trying to identifying who these are photos of.

Photo by:  "S. W. Watrous" (Stephen West Watrous), "Holt Block, Visalia.", (circa 1887).

"Earl Pague" is written on the back of this photo.  I'm pretty sure this is Jonathan Early Pogue (1867-1944), brother to Eva and Genie.  Apparently he just went by the name Earl. (e.g. In the 8/12/11 issue of The Foothills Sun-Gazette, Exeter CA, he is referred to as "Earl Pogue".)

On the back of this picture someone has written "Jim Maffett", which I believe is actually suppose to be Moffett... it's in the same handwriting as the person who misspelled Pogue (writing instead "Pague") on two of the photos above.  Apparently they had a problem with confusing their a's and o's.
The photographer's seal on the back says:  "From S. W. Watrous' Photographic Rooms, Main Street, Visalia",  (circa 1885).

On the back of this picture is written:  Joe Moffett (or possibly Jol Moffett).

And the photographer's seal there reads:  "From S. W. Watrous' Photographic Rooms, Main Street, Visalia, Cal.",  (circa 1885).  

(Updated 9/27/12):  After doing a little research, my best guess as to the identity of the two Moffett gentlemen is that:  The first photo is of  James Blair Moffett,  Born: Mendocino County, 1861.  D: 1915 in Mexico.    The second photo is of Joseph Larkin Moffett, Born: Mendocino County, 1860. D: 1924 in Visalia.  
The two are brothers.   Their family moved to an area not far from the Pogue family in 1866. 
If I have the details right, their father was the half-brother of  Nancy Mayfield Moffett Blair (The grandmother of those members of the Pogue family pictured above.).
