The Glynn is estate 7 in St. Croix’s Queen’s Quarter. Based on appearances on historic maps, the windmill was likely built in the 1750s and decommissioned before 1856. The windmill was incorporated into a dwelling. The inscription on the main entrance keystone says 1810, which is unlikely to indicate a construction date. The windmill tower is in good condition.
The 1750 map indicates sugar cultivation but no structures in estate 7. Neither Beck printing shows a sugar mill icon in estate 7, instead locating a windmill near the border just to the west in King’s Quarter estate 10. This configuration was repeated for all the Beck map variants.
The 1799 Oxholm map shows a windmill in Queen’s Quarter estate 7 with no sugar mill icon in King’s Quarter estate 10. The 1856 Parsons map depicts a tower with no sails in a similar location. The 1921 topographic sheet shows an old mill tower while the later topographic map shows no ruins identifiable as a windmill at Glynn.
The 1750 map attributes ownership of estate 7 to Johan Wilhelm Schoppen & Adrian von Beverhout, with Beverhout also owning King’s Quarter estate 10 just to the west. The maps from 1766 through 1791 attribute ownership of the two estates to Johnston.
