Dennis ...have a look at
www.freebmd.org.uk Deaths Mar 1970
OWEN Florence 7Je1904 Wirral 10a 2507 Scan available - click to view
as it says 7 Je 1904 ...could it be your Florence ( Kelly ) Owen ??
Birkenhead area is on The Wirral ..looks like she moved out of Birkenhead t a few miles away
hmmm - just looked at the other death next to it
Deaths Mar 1970 (>99%)
OWEN Florence 26Au1890 Crewe 10a 970
looks like she was born 26 aug 1890 ....
so
7Je 1904 .. is probably 7th june 1904 - wrong date for your Florence

?
could a more experienced Researcher tell us if 7Je1904 would mean Born on 7th june 1904 please
