I'm looking for information on the JECELIN family from Baltimore, Maryland. My great-grandfather's sister, Bertha E. Killmeyer married John E. Jecelin, Jr. in Baltimore sometime around 1920. They had four children that I know of: George (b. 1/26/1921, d. Oct 1979; Marie (b. 10/21/1923, d. Jan 1978); and the twins, Edward (b. 4/21/1928, d. 5/29/1928) & William (b. 4/21/1928, d. 5/12/1928).
