I hope we might have a connection, but I haven't made it back so far as you have with the COGHLAN line yet.
I am looking for family of and info on Bessie Cleopatra COGHLAN, born in Austin, Travis Co., Texas in August 1893 to Wash P and Jennie COGHLAN. Their family is listed in the 1900 Travis Co., TX census for Austin, Ward 6, ED 92 in Pct 3 on page 99A.
Washington P COGHLAN (b. May 1851, OH) is listed as a carpenter in the Austin, TX directory 1899, 1900; residence was 1401 E. 1st.
Bessie married Oscar Pendleton JONES (b. 23 Sep 1893, Polk Co., TN) between 1910-1912 probably in Travis Co., Texas. They had at least 3 boys: Marvin (b. abt 1912); Clarence (b. abt 1914) and Oscar Roy (b. 16 Jul 1921).
Oscar was living with his grandparents, George and Mary J SHEPPARD in Austin, TX in 1900 and 1910. It is believed that one of their daughters was Oscar's mother and both his parents may have been killed or died shortly after Oscar's birth in Tennessee.
Any information you might be able to offer on the COGHLANs would be appreciated!
