thank you again evie
on closer inspection it looks like Low Railway Street changed its name to Rosslyn Terrace sometime before 1951, and Thomas Street still exsists today, then in between is Burdon Lane ... wow
I have a Davison family living in Low railway Street, a Lumsdon family living in Burdon lane and then Florence Davison married Stephen A Lumsdon and set up home in Thomas Street
now everything seems to fit
thanks again
