I am looking for the parents of Daniel Keiper (September 29, 1811 - May 16, 1881). This is NOT the Lehigh County Daniel married to Susanna!

Daniel married Mary Anne (June 01, 1817 - April 29, 1894) of Bushkill Township, and had at least two children: Richard S. Keiper (June 29, 1849) and Henrietta Keiper (abt. 1855). By 1850, the census placed Daniel in Bethlehem, Northampton County, PA:

(Year: 1850; Census Place: Bethlehem, Northampton, Pennsylvania; Roll: M432_802; Page: 267; Image: 539.)
(Year: 1860; Census Place: Bethlehem, Northampton, Pennsylvania; Roll: M653_1147; Page: 90; Image: 91.)
(Year: 1870; Census Place: Bethlehem, Northampton, Pennsylvania; Roll: M593_1381; Page: 254; Image: 92.)
(Year: 1880; Census Place: Bethlehem, Northampton, Pennsylvania; Roll: T9_1161; Family History Film: 1255161; Page: 311.1000; Enumeration District: 66; Image: 0021.)

I am local and can travel to cemeteries for research, but have not been able to get past this one individual. Any leads would be greatly appreciated!
