Windy,
Need to apologise for red herring. When casting around for old maps I unearthed what I read as "Kirkley Steam" which took me to the St. Leonard's area. However, revisiting the link it actually said "Kirkley Stream"! - shoulda' gone to Sp********rs" or perhaps lack of concentration since I'm listening to the local footy derby and my team is losing.
Do you have the item in the Norwich Mercury, 8 Aug 1885 which mentions "Kirkley steam (small "s"!!) flour mill?" Also reported in the Ipswich Journal 11 Aug 1885.
