Bigler is a far more common name than Pigler among immigrants who went through Ellis Island. Most of them appear to be German or Swiss. I, too, think that Pigler probably is German in origin and likely the same name as Bigler. I have noted a number of instances where B and P are used interchangeably in Hungarian names. The one I am most familiar with is Jozsef Brick/Prick, one of the émigrés from the 1848-49 war. Although he is almost always referred to as Prick, we have several letters from him where he clearly signed his name Brick. Janet
