Haider
A surname of uncertain origin, most likely a German, Arabic, or South Asian name that has been adopted in several languages and regions.
The #8,070 most common surname in the United States (2010 Census) — about 1 in every 75,175 Americans shares it.
Etymology
The surname Haider is not explained by the provided historical excerpt, which appears only as an incidental mention rather than a true dictionary entry. In broader onomastic use, Haider can reflect a German surname related to a descriptive or locational word, or it can be a transliterated form of the Arabic given name Haydar/Haider, meaning "lion." In South Asian contexts it is often connected to Muslim naming traditions and may function as a surname from a personal name.
History
Because the excerpt does not give a surname derivation, the historical path here must be treated cautiously. The name is found in more than one linguistic setting, which means the same spelling may have separate origins in different families. In the United States it is comparatively uncommon and likely represents mixed immigration histories rather than a single source population.

Fun fact
The spelling Haider can point to different origins depending on the family, so two people with the same surname may not share the same ancestral root.
