I am not familiar with the NYC Knipes other than running across them on a regular basis.William and James Knipe appear in the 1840-60 NYC Censuses and Immigration Court Records.To get started, I think you have to began with a couple of major “Knipe” research questions: 1. Most of the Knipe Surname immigrants came from two areas of Europe: a. England/Northern Ireland. b. Germany, Luxemburg, etc. 2. In 1850 (first US Census with all family members names) the Knipes on the East Coast were centered around: a. Pennsylvania (largest number of Knipes). b. NYC Area c. Northern NY and Southern Ontario, CAN. 3. By 1880 the Knipes had moved all across the USA as land opened up in the new territories. 4. The most famous Joseph Knipe was General Joseph Farmer Knipe of Pennsylvania and later Kansas.On the other hand there are 20 to 30 Joseph Knipes listed in the Mormon’s D/B. 5. Recommend working backwards using your grand parent’s vital records and cross referencing with census records.GOOD LUCK.
