OCR failed on this in spite of my attempts to enhance it. Can someone type a text version?
I suppose it’s a representation of the surname "Groleau" but maybe I got the order wrong. When my late father was teaching English in Guangzhou, they gave him a name seal: It’s French Canadian, pronounced Grow Low but unfamiliar English speakers typically assume Grow Loo. If the person creating it only saw the spelling, he/she might have assumed Grow Lei: 格洛雷 géluòléi. But that’s assuming it’s strictly phonetic; perhaps they tried to make some kind of semantic statement.
