Heh, actually I've said this in that chat already. His "ancestry" hadn't awakened the Sharingan at that time. Its's kinda simple to speculate that the crimson-eye was rare, seeing how extremely surprised Madara's father was when he showed it. Despite being what would be seen as a powerful shinobi: "Madara was noted to have been born with very powerful chakra, even by Uchiha standards." Futhermore, grand-people (female line) would leave because of all the war, etc. She was also a house-wife, giving her nearly no way to awaken the KG. If that clears anything up...
