My original immigrant Francis Mansell was "brought over" to USA w/other pudlers and iron workers from England to work a new mine in BOONTON, MORRIS COUNTY, NJ USA. This mine was started by a group of wealthy businessmen from NY and England, headed by a Mr. Scott. I cannot find any immigration records for my Mansell Family (wife Mary Ann and 3 children); nor records on the NJ IRON COMPANY. Would there be a site to check for records in England since the group had at least 33 iron workers brought over together.
