Lovisa
Lovisa is a Swedified form of Louise, which originates in Louis and has been used in Sweden since the 17th century. It was placed in the Swedish calendar in the 1750s after king Adolf Fredericks marriage to Lovisa Ulrika of Prussia in 1744. Lovisa means fighter.
The name Lovisa had a rejuvenation in the 1980s and 90's in Sweden but has since then begun to decline.
Lovisa is placed in the Swedish calendar ( namnsdag) on August 25.
