Hmm, interesting indeed thank you. I did notice that at one time it seemed multiple families living at one house number in Strizovice, maybe this was a reference to that situation. I will take a second look at house number for everything I have for Joseph and his family.
I'm still a little puzzled as to what happened to Rosina after Joseph's death. I can't find a record of her after that in Strizovice, so I don't know if she moved with her son to Vodokrty or... ? Still lots of pieces of the puzzle to fit in, but the picture is getting a little clearer thanks to all the help I'm getting.
