Hello, to my knowledge Adolf Gustav Wallfahrt Haegermann (thus his complete name; b. 1857, d. 1920) was a son of Adolf Wilhelm Wallfahrt Haegermann, who in turn was one of the five known sons of Gustav Hagermann, founder of the Haegermann company. So A.G. Haegermann was a grandson of the "old" Haegermann". Regards, Bahner
