Pam, ‘Hope I can be of assistance to you. In my research I have encountered several Hennefer references. For various reasons I have concluded that your Hennefer and my Henhoeffer/Henofer are two distinct familes. Below are excerpts from the Philadelphia City directory books for 1869 - 1925.
1869 Henifer, Joseph machinist h 337 Bridge, Whitehall
1870 Hennefer, Edward polisher h 337 Bridge, W Hall
1873 Hennefer, Edward polisher h 337 Bridge, W Hall
1883 Hennefer, Alfred grinder h 337 Bridge, W Hall
1883 Hennefer, Edward grinder h 337 Bridge
1883 Hennefer, Sarah dressmaker h 337 Bridge
1883 Hennefer, William E moulder h 337 Bridge
1889 Hennefer, Margaret wid {Edward ?} 337 Bridge W Hall
1889 Hennefer, Alfred grinder 337 Bridge W Hall
1889 Hennefer, William E grinder 337 Bridge W Hall
1890 Hennefer, Alfred machinist h 337 Bridge
1890 Hennefer, Edward laborer h 337 Bridge W Hall
1890 Hennefer, Eliza h 337 Bridge W Hall
1890 Hennefer, Margaret wid Edward h 337 Bridge W Hall
1890 Hennefer, William E machinist h 337 Bridge W Hall
1892 Hennefer, Margaret wid Edward h 2219 Bridge W Hall
1892 Hennefer, William E polisher h 2219 Bridge W Hall

The “Whitehall” in the above excerpts is section of the city. That section name is unknown to me, but I do know the home (h) 337 Bridge St. is presently located in the far Northwest of the city (nowhere near my Henhoeffer’s homes). Joseph was a machinist. 2219 Bridge is not presently a good address in Whitehall section of Phila. Regrettably now, some of the data (didn't have a lot) I had accumulated on the “Hennefer” family has been purged from my files.
1880 Henefer, Annie varieties 66 Blodgett
1882 Henefer, James liquors 66 Blodgett
Annie & James not known to be Henhoeffer/Henofer. May be Hennefer? No present-day street named “Blodgett.”
1924 Hennefer, Wm E formn h 2219 Bridge Fkd
1924 Hennefer, Wm E Jr clk r 2219 Bridge Fkd
1925 Hennefer, Mary (wid Wm E) h 2219 Bridge Fkd
1925 Hennefer, Wm E Jr clk r 2219 Bridge Fkd
“Fkd” stands for Frankford, another city section in the mid-Northeast. These Hennefer people are not thought to be of my Henhoeffer/Henofer family. Also, “h” and “r” 2219 Bridge are NOT the same house. “r” means “rear” An “h” house fronted on the street, the “r” house was behind the “h” house. Yearly City Directories ended in 1930.

Could be either a Hennefer or a Henhoeffer. My guess is Henhoeffer/Henofer, one of my relatives. I could be wrong!
