I found the following online on the website titled Haskell Family History
http://www.haskellfamilyhistory.com/database/3/44232.html
There are two sources for the information below:
1)Charles Thomson III Haskell, compiler, "Descendants of Anthony Porter Haskell 1875-1941"; report to Haskell Family Association.
2)Ira J Haskell, Chronicles of the Haskell Family (Lynn, Massachusetts: Ellis Printing Company, 1943).

Anthony married Sarah Ann BLACK on 17 April 1901 (Sarah Ann BLACK was born on 22 May 1879 in , Richland, South Carolina, United States, died on 6 July 1902 in Shandon, Richland, South Carolina, United States and was buried in Shandon, Richland, South Carolina, United States.) Note: Shandon is a section of Columbia, more like a subdivision. Elmwood Cemetery is not in Shandon.

Anthony next married Loraine SMITH on 5 August 1903 (Loraine SMITH was born on 3 November 1871 in Thedford, , Ontario, Canada and died on 21 June 1906 in , Richland, South Carolina, United States)

Anthony next married Grace CHAPPELL on 7 November 1907 in Shandon, Richland, South Carolina, United States (Grace CHAPPELL was born on 14 November 1885 in , Richland, South Carolina, United States and died on 14 April 1916 in Shandon, Richland, South Carolina, United States)

The photograph of him was also found on the Haskell Family History website. I do no know who originally downloaded the photo.
