Q. Would you have any information on mirrors from John J. Kinsella Co.?

The John J. Kinsella Co. was in existence from 1872-1931 and was one of the larger firms producing stained glass and mirrors in Chicago at the time, employing some 50 people, according to the publication, Frueh's Chicago Stained Glass.

You can see stained glass windows by Kinsella in the following Chicago buildings:

• St. James Lutheran Church - 2048 North Fremont Street
• St. John Berchmans Church - 2519 West Logan Boulevard
• St. James Chapel Quigley Preparatory Seminary North - 631 North Rush St. -- Seminary Chapel
• St. Mary of the Lake Seminary - Mundelein, Illinois.

The St. James window is particularly noted by Frueh as "of exceptional technical and artistic merit" particularly the Gethsemane window.

Apparently John J. Kinsella was quite an accomplished artist.  There was a 2007 exhibition of his stained-glass work at the Community Hall of the DesPlaines Valley Public Library in Lockport, where Kinsella lived.

This is from an announcement of the exhibit:

"Kinsella was raised on a farm between Lockport and Joliet, and at the age of 21, established his own studios in Chicago's Little Italy neighborhood.  He helped to pioneer the "Favrile" style of glass invented by John LaFarge and L.C. Tiffany and his works, considered equal to the great masters' landmarks, decorate many Chicago and southwest suburbs' cathedrals.
More than 200 images depicting stories of the Old and New Testaments are seen in the photographic essay that chronicles Kinsella Studios' most outstanding and award winning glass canvasses. Among these are The Memorial Window at St. Dennis  Catholic Church in Lockport, God's Promise at St. John Berchmanns in Logan Square, and the world famous Lancet Windows of St. James Chapel in Chicago.
The St. James windows alone required six years to be installed and are composed of fifteen individual lancets that stand nine feet wide by forty feet tall. The early 20th century hand painted masterpieces replicate those at St. Chappelle, the Reliquary in Paris which holds the crown of thorns worn by Jesus at the cross."

There are advertisements and directory listings for Kinsella glass and mirrors found in searching various online full-text repositories, but they don't say anything about the actual products or show any images. Kinsella died in 1915, but his company stayed in business for another 15 or so years.

They did make and sell mirrors, but most of the available sources are centered on their stained-glass products.

It is possible that the Chicago Historical Society or the Lockport Historical Society would have information on this aspect of the company.
