Spanswick One Name Study
Spanswick Births, Marriages, and Deaths in Ireland (1845-1958)
Spanswick's references are very rare for Ireland and only two have been found in Civil Registration. The "Male" Birth is probably Thomas H Spanswick (who also appears in the Index to Regimental Births for 1884) and Noah Spanwick was baptised in 1860 at St.James Southbroom, Devizes, and can be located in the Wiltshire Parish records (link above).
