Hello,Bones 91.
If allowed so: did you ever look for the maps from the WW2 concerning Warthegau?
Or Westpreussen? You could follow such path:also the military maps from the year 1945.
With the battles,displacement of troops.Also with the locations of military troops.
Maybe they will be sufficiently accurate to show the town of Strelno with the street
layout?Maybe something of them avoided burning down due to wartime events?
There also is a supposition that some lesser important streets of there got back their old
names from the former Prussian times after the wartime events of 1939.
Anyway may you look in place for the old Prussian maps.And may you try to look for
the societies grouping the former residents of Strelno within the said period of years
and made to move to the Germany after the year 1945.All this is possible to be done
with yourselves in place.Myself I live far away of Strelno and can not visit it
to help you more.
I got the following link when requesting the map of Strzelno (Strelno):
https://www.google.com/maps/place/Strze ... %2F0266k1kafter having put ot Google the following tag: Strzelno plan miasta (Stadtplan,map of the town).
If you have got any further details from your still alive relatives regarding the vicinity of such location of street,
e.g. proximity of a church, city hall etc.this could be an indication for your further seeking.
I tried to find a Barn Street (translated now from German into English):I didn't find any its Polish equivalent
in the said town plan.
That said, I wish you of a Happy Easter and express my regards.
Jack
