Hey Paul! I was told by a long lost relative that the Catherwood (my surname) was derived from Calderwood. My great Uncle Is the Architect Frederick Catherwood, but that in and of itself is a quagmire, practically no info on him. every time I research i get bogged down, maybe from that direct correlation. If you've ever heard of Catherwood roots, I'd appreciate any info. Cheers!
