Over the last few days I’ve been popping “Kerlen” into browsers and a myriad of Genealogy sites in the hope of finding more Kerlens, more information, anything! I started at the most logical place. The top of our known family tree. There’s not much around about Gerard Kerlen. It’s like he just appeared from nowhere and decided that Zutphen was the place he’d like to live and start off a family called Kerlen.
