Justina Gärtner was born on May 12, 1862 in Kiliansberg-Veitsteinbach, Kreis Fulda, Hessen, Germany.

She was the daughter of Andreas Gärtner and Margaretha H. Hosenfeld.  Justina grew up in the family  home, Kiliansberg 12 - the house name was  "Jule."  I found an old photo of this house in the Veitsteinbach 1050 anniversary book on page 209:

Roughly translated this says:

(above the photo) The house Kiliansberg 10 was formerly Number 12, and the house name is "Jule". One-story living house with barn and stable. House was completely reconstructed at the end of the 60s.

(bottom paragraph) Probably built by Andrew Gärtner. He and his wife, Eva Maria definitely lived here in 1865. [NOTE:  This is incorrect, since Maria Eva died on Oct. 11, 1853--Andreas was living in the house with his second wife, Margaretha Hosenfeld, and their children in 1865]

Justina was 20 years old when she arrived in the United States on June 19, 1882 on the ship Elbe.  The port of embarkation was Bremen.  At a service speed of 15 knots, this ship was very fast for its time.  The trip across the Atlantic should have only taken approximately 8-1/2 days to complete. Her brother, August, was already in the United States, having arrived two years earlier.  Supposedly, her mother, Margaretha, accompanied her on this trip, but I was unable to find her in the passenger ship list, so I do not think that this is true.

The "Elbe" was built by John Elder & Co, Glasgow in 1881 for North German Lloyd of Bremen.  She was a 4,510 gross ton ship, length 416.5ft x beam 45ft, straight stem, two funnels, four masts, iron construction, single screw and a speed of 15 knots. There was accommodation for 120-1st, 130-2nd and 1,000-3rd class passengers. Launched on 2/4/1881, she sailed from Bremen on her maiden voyage to Southampton and New York on 26/6/1881. She was a record breaking ship at the time and sailed from Southampton to Sandy Hook in 8 days 12 hours 50 minutes, and in the Easterly direction in 8d 9h 10m. She sailed from Bremen on her final voyage on 29/1/1895, and the following day was sunk in collision with the British ship "Craithie" in the North Sea with the loss of 322 lives.

She married Damian Huerich on August 9, 1892 in Allegheny City, PA.   Damian was born on Dec. 25, 1858 in Steliberg, Prussia, Germany.  Here is a photo of Damian, taken with his parents in Germany.

Damian  had previously married Caroline Gimber on Oct. 30, 1888 in St. Mary's Church, Pittsburgh, Pa.  She was born May 13, 1858 in Indiana, Spencer County and died Mar. 2, 1892 in Pittsburgh, PA.  She was the daughter of Andre Gimber and Eva Roeser. Damian used several different spellings of his last name, including: Heurich, Henrich, and Heinrich.  Damian had arrived in the United States on March 29, 1881 when he was 22 years old on the ship Salier.  This ship departed from the port of Bremen and the manifest # was 36013.  At a speed of 12 knots, the voyage should have taken approximately 11 days to complete.  He listed his occupation as "joiner" at that time (a skilled carpenter.) 

The steamship Salier was built in 1874 by Earle's Shipbuilding & Engineering Co., Hull, England, for Norddeutscher Lloyd (North German Lloyd).  This ship weighed 3,083 tons; was 107,59 metres long x 11,91 metres broad; had a straight bow, 1 funnel, and 2 masts.  It was iron construction, screw propulsion, and had a service speed 12 knots.  It had accommodation for 142 first- and 800 3rd-class passengers. 15 June 1874, launched; 14 July 1875, trials held. 8 September 1875, maiden voyage, Bremen-Southampton-New York (3 roundtrip voyages). 1 April 1876, first voyage, Bremen-South America service. 10 February 1880, last voyage, Bremen-South America Service; returned to Bremen-New York service. 1890-1891, triple-expansion engines by Vulkan. 10 December 1895, resumed Bremen-South America service. 7 December 1896, wrecked on the north coast of Spain with the loss of her entire complement of passengers and crew (279 people).
