Help, please!

I am looking for a LANG/LANGE family >from Philadelphia: Jacob Lang,
Jacob W. Lang, Louis Lang, and Isaac M. Lang. The name is spelled both
ways in city directories >from Philadelphia >from 1879 on.

from about 1882 to 1896 Louis LANG, along with Moses STERN and Samuel

M. MAYER, was affiliated with Lang, Bernheimer & Co., a wholesale liquor
business.

If you have any information about this family or their descendants,
please let me know.

Thank you,
