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.[1] The entry includes some relevant genealogical information for Buggy.
You can read the publication here.
