There is only one Towle family in 1881 census - Mrs Mary Towle (born England) with some 11 children - judging from birthplaces the family came to Ramsey from England c.1864 (apparently not in 1863 directory) - she appears in directories from 1881 to 1894 initially at Summerland then 6 Ballure Rd - this period was the time when Ramsey Shipyards were in full swing and many (mostly Scots) came to work there.
