Hello.
I am trying to find some information on my great grandfather Gottlieb Kroll.
He was a carriage builder in Philadelphia, PA. According to a city directory his business address in 1890 was 1310-12-14 Wallace Street and his home address was 1526 North Street. He built Abraham Lincoln's funeral hearse, received the Franklin Institutes' Longstreth Award in 1896 (subject: Engineering; topic: Convertible Carriage), Authored Revelations in Carriage Building (Publisher: Philadelphia : Ware Bros., [1897]), and was awarded a US dated 7 May 1895 for an innovation regarding convertible carriages.
Gottlieb had 5 children .. Marguerite, Mable, Nellie, Jen, Lilian and my grandfather Frederick Kroll (b. Jan 1912; d. Jan 1986).
The family has passed down the story that Gottlieb was related to Jospeh Kroll, owner of the Kroll Opera House in Berlin, Germany. I have acquired information regarding Joseph and his family on the chance that the story is accurate, thus, if anyone is looking for information I would be happy to pass along what I have learned.
If anyone has knowledge of Gottlieb and/or his family I'd be grateful to hear what you have learned.
