Yes. Pretty much. The first settlers to that township were originally from Elsas and they petitioned to name the township after that location. For more information on the early formation of Berks County’s townships, check out: https://archive.org/details/cu31924028852196. That is the link to an early history of the county. Hope that answered your question!
I know this is a very belated response, but I just discovered your blog and I’m reading every entry with great interest. My family has deep roots in Berks County, and Reading in particular – and they go way back. I rarely read a list of pioneers in the area without seeing at least a half dozen family names on the list. I’ve been researching my family history since I was five years old, and have amassed an enormous amount of material but am always looking for more, and to fill in the many gaps I still have. I wish I could visit the Henry Janssen Library, but I live in Vermont and have to do my research from a distance. It’s thrilling to see that you’re cataloging the collection and digitizing it. I feel sure there are many items I’d be interested in seeing that have been invisible so far due to not being cataloged. Having done a lot of online research, I know that it’s all too common for items to disappear because they haven’t been cataloged or have been transcribed incorrectly. I look forward to following your blog, and your progress in sorting out the library’s collections.

Is Alsace named that because settlers came from Alsace Lorraine?
