I have no details on the two daughters yet, but have confirmation that the two boys & their parents immigrated to New York City circa 1877.

He 'Americanized' his name into Lawrence & began a business named Lawrence Yosco Manufacturing Company where he created musical instruments like mandolins and banjos.(Many are still in existence & being traded on eBay constantly!)
