Cartographer: one who produces maps.
When ancient mariners returned from their voyages of discovery, they turned their records and logs over to monastic type individuals (map makers, cartographers) who would turn that data into maps which other mariners would use on subsequent journeys to the same regions.
When those mariners returned, they turned their new records and logs over to same monastic type individuals who would then use the new data to make corrections and improvements to those maps, and then produce new maps that other mariners would use on subsequent journeys to the same regions.
Over the centuries many have journeyed to ancestral regions and brought back their findings. I am comparing and distilling those findings, digitally connecting the dots of recorded history according to where the experts say they should be connected, and producing new maps of generation-by-generation ancestral pathways that zigzag through thousands of years of recorded history through the lives of actual people.
Most of these maps have never been seen before, and visually following one’s curiosity through the world’s largest maps of human genetic migration can be truly fascinating and enriching.
