I have looked through all of the records that I can find, and have identified a possible Emily DeLoach that could be the one you are seeking.

Riley DeLoach married Dora Ann "Dory" Mathis on 5 March 1843, probably in Lowndes County, Georgia. Their family is listed in the 1850 Lowndes County, GA Census:

1850 Lowndes County, GA Census
From the index
Riley DeLoach 30 GA
Dord(sic) Ann 24 GA
Thomas 5 GA
James 4 GA
Hiram 2 GA
John 6mo GA


Per Dora's application for Bounty Land as a widow of a soldier who served in the Indian War, Riley died on 3 April 1852:

ABSTRACTS OF PENSION & BOUNTY -LAND RECORDS for service in
the Rev War, War of 1812 & the Indian Wars RILEY DELOACH, of
Lowdnes Co Ga, Indian War soldier On Nov 28, 1850, in
Lowdnes co before William Patter, JP, personally appeared
RILEY DELOACH who made his declaration to obtain bounty-
land under Act of Congress passed Sept 28, 1850; that he was
a private in a company of volunteer Militia commanded by
Wm. C. Newbern in the Florida Regiment commanded by Col
William Bailey, in the Indian War; that he volunteered at
Sandy Ford in FL. 9/20/1839, for 3 mos & was honorably
discharged at Fort Fanning 12/20/1839.

On April 22, 1853, Mrs DORYANN DELOACH, age 37 yrs, made
her declaration before Wm. Smith, JP in Lowndes Co Ga to
obtain bounty-land under same Act of Congress. Husband's
application above apparently had never been approved. She
stated she was the widow of said RILEY DELOACH and that they
were married in Lowndes Co 3/5/1843, by Shadrach Griffin,
JP and that she was DoryAnn Mathis before marriage;that he
husband died in said county 4/3/1852. John E. Mathis & M.A.
Mathis vouch for her as said widow & for the death of said
Riley. Attached is a certified copy of the marriage
license from Lowndes Co marrriage Records. She was granted
120 acres of bounty land 9/26/1856. On 9/24/1869, she made
her declaration before D.D. Mahon JP at Stockton, Clinch Co
for adfditional bounty-land and was vouched for by Wm.M.
Tyler & R. DELOACH; no action was ever taken on this
application.


Dora and her family are listed on the 1860 Lowndes County census:

1860 Lowndes County, GA Census
Troupville
Household 128
Dorian DeLoche (male) 33 GA
Thomas 16 GA
James 15 GA
William 13 GA
Hiram 12 GA
John 11 GA
Wealthy A. 6 GA
Emily 3 GA

Note the variant spellings of Dora's name, the DeLoach surname, and the mistake on the census identifying Dora as male. I have searched the census records of Georgia and Florida (Lowndes County borders Florida) using every variant spelling of Dora's name, and could not find a further listing for her, or her daughters that were born after Riley's death.

To further confuse the issue, Hiram DeLoach married Emily Sweat, who was born in Florida. They had a daughter named Weathy DeLoach. In the 1880 Lowndes County, GA census, Hiram's wife is listed as Emily DeLoach, born in 1853 in Florida.

Dora died on 17 Aug 1895. She and her son James are buried in the New River Cemetery in Tift County, GA.

I could not find any record regarding John Charles Farren. I did find his widow Emily(Emiline) DeLoach Farren in the 1900-1920 census records. As you know, she and her daughter Mamie DeLoach Farren Ruff are buried in the Ruff Cemetery, Cobb County, GA.

Perhaps some other researcher of the Riley DeLoach family has found additional information and can share it with us.
