Are you related to the Thiemes of the Thieme Publishing Co.?My husband's gggrandfather was Gerald Thieme from Haarlem.He was married to Catharine Behrends (Barends) and had 2 sons, Derk Anthony (b. 1882?), my husband's ggrandfather, and Johan Frederick (b. 1883) both born in Netherlands but the family immigrated to California when the boys were young.I have been trying to trace the family back in the Netherlands with little success.I'd appreciate any information you may have. Thanks.
