Our family owes much of our interest in genealogy to Iva Mickler Canova who married Bernard Halsema, Anthony Halsema, Sr.'s brother.
Most of the in-depth primary links on The Leonardi Home Page are Leonardi families that are in the direct line of the Halsema family or are very short branches off the trunk of that tree.
To view the entire Leonardi line, use the link for Genealogical database. There you will find many different ways to search. For the sake of consistency we chose to use the spelling Leonardi.
