Well, like everyone they originally came from Africa. Later, they chilled out in Europe for a few ten thousand years.
Interestingly enough, Africans have white children with a surprising frequency. The reason that they are mainly dark toned is the fact that light skinned people (without proper social acclimation like hats and sunscreen) die from exposure with alarmingly regularity. So saying that white people evolved from black people isn't necessarily true. From a biological perspective, white people devolved from black people by losing the ability to produce a certain type of melanin. But then, black folks need Vitamins A&D added to their food in temperate climates since they can't absorb key UV rays in the winter.
Bloodlines themselves are actually quite complicated of course - as Europe was often subjected to migrations and warfare, which of course complicated matters. For instance, the Aryan "race" comes from India Not where you might expect white folks to come from. But this over complicates things so we can probably safely ignore it.
White people simply adapted to the lack of UV radiation in high latitudes. In the scientific categorization of skin colors (based on tanning potential) - "white" people encompass type 1,2,3, & 4 of the 6 skin types. Ranging from very white (as you might expect from Irish or Scandinavian people) to the olive skin often referred to as Mediterranean. Simply put, people with lighter skin adapted from people who did not need dark skin to protect themselves from sun - and in fact received more vitamins with lighter skin (and various sexual selection factors too).
As a quick note, I'm not sure your other skin color origins are at all accurate either. Black people didn't come from Jamaica or Haiti - Native Americans lived there first. Spanish people only come from Spain - but Latinos are often mixes of varying Spanish and Native American families.
Anyhoo, this will probably help you out more...
