Wilsie is a distinct and uncommon given name, believed to have originated from Scottish origins. It is derived from the Gaelic 'Gilleasbaig', which translates to 'devoted to Saint Basil'. This name has been popularized by its association with the Wilsies of Scotland, a prominent family in Aberdeenshire known for their contributions to society and politics.
"Wilsie experienced a peak in births during the early 1900s, with six babies born in both 1912 and 1933. The decade of the 1930s saw more activity overall, with fifteen babies born compared to only eleven between 1912 and 1918."
