Christoph Ludwig Friedrich "Ludwig" Heiden was born on May 19, 1826 to Johann Jochim Diederich Heiden and his wife, the former Wilhelmine Dorothea Sophie Schmelz. He was a younger brother of Maria Heiden and, therefore, uncle to August Heiden.

On January 27, 1883, Ludwig sent a letter to his nephew, August Heiden. He had been living in Sweden (the letter came from Christianstad, Sweden, now Kristianstad) and had been married to his second wife, Cecilia or Carolina Grönqvist who was born July 10, 1832,  for 20 years at that time. He would have been about 58 at that writing.

According to a Household Survey for 1901: Ludwig moved into Kristianstad stadsförsamling in 1888 - Occupation Skradderemartare  - Tailor repairman - Sigrid Olsdotter was living in as a maid

Ludwig died on April 23, 1912 at 86 years of age in Kristianstad, Sweden.

From a first marriage, Ludwig had four children which he described as follows:

1. Luise is married to a tailor in Denmark
    
2. Ferdinand Ludwig Theodor Heiden is a Catholic priest in Copenhagen.
    
3. Wilhelm Friedrich Johann Ludwig Heiden is a tailor and lives in Gorlitz, Silesia.
    
4. And the youngest, whose mother died when he was 18 months old.

From his second marriage to a Swedish woman, he had two children.

1. Georg, has been in business for four years
    
2. Oscar Peter Rudolf Heiden

Malchin County, Mecklenburg Schwerin

Alma Maria Sofia Heiden born about 1866 to Ludwig and Cecilia in Kristianstad, She died on May 27, 1869

August Heiden's Uncle Ludwig was living in Sweden according to an 1883 letter we found. He had four children by his first wife who was German and two more by his second wife who was Swedish. Some of his children were living in Sweden but others had settled in Denmark, Silesia (central Europe) and one son emigrated to Boston, Massachusetts. Of course, these would be August's first cousins and would share about 12.5% of DNA with him. This probably accounts for the appearance of some of the geographic regions represented in my DNA results.
