I am not sure if I can be much help but my family line intersects with Peidl, though I don't have much detail.
I have some names, they are;Alex Peidl, Tony Peidl, Mary P. Peidl. Mary Piedl was the daughter of Hannah Holzinger, she married Otto Lock (Locke) and had 3 children, May, Florence and Otto.
My information is very sketchy at best, I am going by a lot of family that met these people 60 years ago as children and there memory of events are not always 100% correct.
Mary P. Lock could stand for Mary Peidl Lock or not.
I am pretty sure she is the daughter of Hannah and beleve they came from Germany. Hannah ran a resturant in Philadelphia, somewhere around 5th and Callowhill till her death in 1908, where here current husband Otto Locke took over and then married her daughter Mary P.
I do know that there was a Mary and she married Otto, a plumber farmer and 3 children as mentioned above. The last name is a logical guess at best
I have been told 4 last names for Hannah, they are Holzinger, Peidl, Brown and Lock, she is burried under the Lock name along with Mary and Otto.
I have These dates
Hannah b. 1862 d. Abt. September 25, 1908
Mary P. b.1887 d. Abt. August 25, 1914
Otto Lock b.May 30, 1864 d.March 17, 1960
