[NOTE: "United Kingdom of Great Britain and Ireland" was that country's formal name 1801-1922.]

His address at the time was 606 East 14th Street, New York, New York 10009-3311, Lower East Side (torn down).

Her address at that time was 1332 3rd Avenue, New York, New York 10075-1902 on the Upper East Side. She worked in a candy store owned by her parents.

Mary's parents were John Buckley (?-?) and Margaret Buckley née Monehan (?-?).

By 1920 Gustav and Mary had moved uptown to Assembly District 23, Enumeration District (E.D.) and Tract unknown. A.D. 23 covered a vast area and their residence was probably 509 West 179th Street, New York, New York 10033-5708 (built 1919) in Washington Heights where they lived for decades with their children.

Gustav and Mary were both buried in Gate of Heaven Cemetery, 10 West Stevens Avenue, Hawthorne CDP, Mount Pleasant, Westchester County, New York 10532-2205, Section 44, Lot 511, Grave 15.

[NOTE: In 1968 it was disclosed that a possible unidentified infant was buried with Gustav. It's highly unlikely they waited four years to have children and a stillborn or other infant death is highly possible. If it had been a girl, she would have been named Mary after the mother as was the custom. On the other hand, the infant could be Marie Gerardette Kantz erroneously Mary Kantz who was born and died in 1964.]

ANECDOTES:

Nana often recited the Lord's Prayer in Irish, or Gaelic as she called it.

While still in Ireland, Nana and her friends would often cross a pasture and provoke bulls into charging "by lifting our red petticoats".

In New York, Nana said that "when she was a girl" to call someone a Hessian was very insulting, a vestigial memory of the Revolutionary War.

Nana's rendition of Too-Ra-Loo-Ra-Loo-Ral (That's an Irish Lullaby) (1914) was very moving.
