I have previous come across references to Buggy’s from Waukon, Iowa in a US newspaper obituary. History of Winneshiek and Allamakee Counties, Iowa contains a few paragraphs about a metal work firm that was owned and operated by James Holohan and Michael Buggy in Waukon. The entry includes some relevant genealogical information for Buggy.
You can read the publication here.
