Scott, I am thrilled to see your message! We may be able to really help one another. My mother is also a great-grandchild of Wilhelm and Wilhelmina Allenberg. Her mother was Lucy (Allenberg) Ruediger, who was the daughter of George Allenberg and Sara Sickles. George was the son of Wilhelm and Wilhelmina. My family still owns the farm in Millerstown! I have several pictures of Emma Allenberg (Callen), and some of the other relatives as well. My aunt has the originals, and I have great copies. I know you said that Emma was the only child born in the U.S., but my records show differently - William born in 1886, Emma in 1891, George in 1888, and Henry in 1889 are all later than your date of emigration in 1884. As Mr. Gavalek stated, we can also trace Allenbergs to Montana. One family moved out there several decades ago, and a few are still out there. My question to you is regarding Wilhelm and Wilhelmina. I have little info on them beyond a birth year for each. I would love to know about their emigration - when, where, and especially, from where. I also have the wedding photo of them that you spoke of. My family's verbal history states that Wilhelm was sponsered by a brewery on the N. Side of Pittsburgh. He came over first, and then sent for Wilhelmina later. They came to the U.S. via Philadelphia. They lived on the N. Side for a while, then bought the farm in Millerstown. Rumor says they came from "Germany" but that's really all we know. I would love if you could share your info with me! Please let me know if you have any other questions I could help you with. Thank you so much. This has made my day!
