Dear List, I have been trying to trace a Catholic family who claim to have emigrated from Aachen in 1881 (but I think the date may be off). The husband was Jacob Mossinghoff (1851-1915), from Holland, according to the family story. The wife was Elizabeth Anna Koch (1862-1952), maybe from Essen. Which list(s) should I try? I've apparently gotten the wrong ones so far. Any help is appreciated. Leslie
