Thomas F. McCormack worked in the Revenue Department of the Staten Island Ferry in New York City.

The great wave of Irish immigration to New York made the city an important part of the Irish Diaspora.

(Until very recent years, Irish surnames were prominent in the Fire Departments, Police Stations, and city offices of New York.)

At his business address in the “Department of Docks”, Mr. McCormack received a postcard from Ireland.

The postcard was sent by Terry, who was enjoying hugely a visit to “dear little Ireland”.

The face of the postcard is a black and white photograph of the Convent of Mercy at Ennis, in County Clare.

The postcard photograph was copyrighted and published by Lawrence of Dublin.

On the reverse, we see that the greeting was mailed from Dublin, Ireland in July of 1938.

The convent was part of a large complex of buildings including a school, an orphanage, and a laundry.

(In recent years, there have been several investigations of human rights violations at some of the schools, orphanages, and laundries, operated by religious orders in Ireland.

In a quick survey of internet databases, I did not find any scandal attached to the Convent of Mercy.)

As the number of religious sisters declined, the large complex was largely torn down or re-purposed.

The Order of the Sisters of Mercy now occupies a smaller building in Ennis, and the former convent complex now houses a museum and a hotel.
