Thanks for your reply. Unfortunately, I am stuck on Heinrich. Have no siblings or parents yet. He died in Bandekow and his widow Wilhelmine immigrated to the US. No more info on Heinrich. Feel free to keep in touch at firstname.lastname@example.org
Will let you know if I find out any more on Heinrich. Bandekow and the Janke/Jahnke name only connection right now. Do you have any info on the town of Bandekow?
