I will get back to the two posters here individually, but I shall be rather short of time over the next few days, so I'm just posting here so that they know I'm still on the case, as I haven't really investigated the Drehers sideways....have just looked at Christian. My mother has confirmed that the Salford relatives were Drehers. One of Christian's sons became a pork butcher, but then he married a pork butcher's daughter & Christian's best friend in Nottingham was a German pork butcher. Mmmmmm......
I've always wondered why Christian & his wife left their adult children & Christian's brothers behind in Liverpool & moved to Nottm (apart from the football). Nottm had, in fact, a thriving & growing German community working in the lace factories, so maybe he thought there would be new opportunities for his family....maybe as told to him by his relative, John, in Derby. If we could only find them in the German records, we'd be able to find out if they were related.
