Received an email from Shirley Murray who gave me updated burial information on David L. and Ellen (LAMBERTSON) MENGLE. Both are buried in the Holp Cemetery in Jackson Township, Montgomery County, Ohio.
Ellen (LAMBERTSON) MENGLE was my maternal 3rd great-grandaunt, the sister of my ancestor, Carey W. LAMBERTSON. Ellen was born June 21, 1850 in Ohio (probably Butler Co.) and died September 16, 1933 in Jackson Township, Montgomery County, Ohio. She married David L. MENGLE on November 10, 1870 in Butler County, Ohio. David was born circa 1851 Ohio, the son of George and Susanna (RUMBARGER) MENGLE. David died July 4, 1938 in Jackson Township, Montgomery County, Ohio.
David & Ellen had one known son, Lionel C. MENGLE, who is also buried in Holp Cemetery, along with his wife, Edith. According to Shirley's email, Lionel was born in 1885 and died in 1961 while Edith was born 1887 and died in 1947.
One of the benefits of posting information online is that oftentimes a researcher or cousin will contact you and give you a tidbit of data to add to your files. Now I will set up a memorial page for them at FindAGrave.
