I am a former resident of Cortland County and wrote a History of Taylor (Cortland County) in 1977 after many years of extensive research of the town. In my collection, I have the obituary of Charles Cotanche, 1994, which states he was buried in Union Valley Cemetery in the town of Taylor, Cortland County. I moved to Florida the next year and do not have a copy of Laura's obituary, but would suspect that she was also buried in Union Valley.

However, I notice that he is listed under Cortland Rural Cemetery on www.findagrave.com, but his obituary from the Cortland Standard clearly states Union Valley. His funeral was at Perkins Funeral Home in Dryden, but Laura's is not listed in their 2005 archive. Sorry I could not help further.
