I sent this information a couple of days ago, but don't see it posted, so here goes:
Anna M. and Joseph F. Baumgart are buried in the cemetery at Trinity Lutheran Evangelical Church in Joppa, Harford County, Maryland.I have a photo which shows part of their tombstone, and can send you a copy if you like.
The1880 census for Abingdon, Harford County, Maryland has John (age 42) and Ida (age 52) Dollenger, with children Anna M., age 17, George C., age 13, and Sopia T., age 10.John worked for the railroad.The census says that John and his parents were all born in Maryland.Ida was born in Hanover.All of the children were born in Maryland.
John, Ida, and son George are also buried at Trinity Lutheran, and I have a photo of their tombstones as well.
John, b. June 15, 1836, d.d May 29, 1917 Ida, b. Sept. 20, 1825, d. Oct. 4, 1901 George, b. Feb. 8, 1867, d. June 9, 1912
I found George and his family in both the 1900 and 1910 censuses, living in Magnolia, Harford County. He and his wife, Anna B. C. Billmyer, were married about 1894, They at least eight children, seven of whom were still living as of the 1910 census.
After George died, his widow married my great-grandfather, William C. F. Kammerer (in 1914—I believe she died later that same year).
I have a little more information about George and Anna's descendants, if that would be helpful.
