Holm had a relationship to a girl named Arlette Lund during his years in Aalborg. In 1851 it resulted in a son, Ferdinand Jørgen Peter Holm, but Arlette Lund's parents, who were wealthy restaurateurs, would not let their daughter marry him. Holm later wrote her many letters but she ended up marrying another man. After his return from America, in 1861, Holm married Emilie Bendixen (30 May 183? - 27 August 1914), a daughter of captain Boy Bendixen, his collaborator in Åbenrå. They lived in
Nyhavn after moving to Copenhagen. He made several large donations to the church, a children's asylum and a new school in Nykøbing Mors. The school is still named M. C. Holms Skole ("M. C. Holm's School") after him. The local Freemasons Lodge is also named Lodge No. 67 "M. C. Holm" after him. Holm died on 23 September 1892 from
appendicitis. He is buried in Nykøbing Mors Cemetery. Peter de Nelly Brown took over the management of the company after Holm's death. The company's next new ship was named
M.C. Holm in 1894. Helsingør Jernskibs- og Maskinbyggeri closed in 1983. The buildings were repurposed into a cultural centre named
Kulturværftet, which opened in 2010. In 2023, the musical
Horisonten opened at Kulturværftet. The musical was written by Anna Karlin and Albert Mikkelsen and centered around the opening of Helsingør Jernskibs- og Maskinbyggeri, Holm's relationship with Arlette and his marriage to Emilie, and Ferdinand's attempt to reunite with his father. Holm was portrayed by
Magnus Hauge Nielsen. == References ==
