How many children did Johann Sebastian Bach sire?

This dude was busy!

Bach himself died in 1750.he had earned an adequate income but it isn't as though he was earning royalties on his many exceptional compositions. when he died his income stream dried up and whatever savings and assets they had accrued quickly ran out. Times were tough back then even in Europe.

busy man!( and woman!)

I answered 14, which is about the number that survived infancy. Were there rumours of illegitimate children?
