*) From: “Bijdrage tot de geschiedenis van Retie”, Edward Seyens, 1949 (Drukkerij G. van den Eynde, Retie, Uitgeverij De Berk, Retie) page 85:
Striking is the precense at Retie, in the years 1750-1790 of several Swiss glaziers, who with their glaziercoffin on their back travelled threw the villages. We name Jan Antoon Morel, the brothers Peter Antoon and Jacob Baes, from Bielandszoone (Bellizona), Jan Baptist Lasters (Latters?) from Aussaime, Andries Marniet, also from Bellizona, Peter Wallida from Claes (?), Jozef Prono from Sancta Maria de Jubiasco (near Bellizona). The last one disposed of by will to his uncle Jacob Prono and to his sister Maria Madaleen. He died at Retie and was burried there on 14 juli 1761.”
