David Davies/Charlotte Von Steuben, PA

Looking for info on Charlotte Hannah Von Steuben who married David Davies, she was b. Allentown, PA, her parents were August Lewis Von Steuben b. 1 May 1843 and Ellen Amanda Lawall, hoping to find siblings and children and parents of David Davies, I am guessing Charlotte and David Davies were born abt 1860's and married abt 1880, would appreciate any help.
Thanks
