• Alpha thalassemia silent carrier
• Alpha thalassemia minor, also called alpha thalassemia trait
• Hemoglobin H disease
• Alpha thalassemia major, also called hydrops fetalis
• Beta thalassemia minor, also called beta thalassemia trait
• Beta thalassemia intermedia
• Beta thalassemia major, also called Cooley's anemia or beta-zero (ß0) thalassemia
• Beta-plus (ß+) thalassemia
• Mediterranean anemia

Thalassemia is an autosmal recessive blood disease. That means that it is an inherited disease. Thalassemia in more common in Mediteranian people.

Very unlikely. Thalassemia is an inherited disease, affected persons are born with the genetic disorders.

However, silent carriers (Alpha Thalassemia, 1 gene defect) or Beta Thalassemia Trait (1 gene defect), do not have significiant symptoms. Consequently, if this person did not have any relevant blood tests till the age of 20, he/she might no be aware of having the condition.

That's only a hypothetical suggestion.

Yes, A "carrier" of alpha thalassemia and of beta thalassemia can marry, but not to someone with any hemoglobinopathy.
