I've found additional information on this family.
Laura Meling is reported to have had relationships with a man named Jacob Jacobson and producing a daughter Emma. Laura Meling is listed on the passenger ship in 1887 with 2 year old daughter Emma coming from Russia. They were actually from Norway, but boarded a ship in Russia. Emma doesn't have a last name listed on the record.
In a 1925 census Emma's father is listed as Jacob Jacobson.
