How many of Johann Sebastian Bach's 20 children lived to adulthood?

I am not a big history buff, but this game question about Johann Sebatian Bach is so packed with information. it is a wonderful read of a man born in 1685 and died in 1750 is an amazing life to have had 2 wives in his life. 1st wife gave him 7 children and his 2nd wife 13 children. Not heard of in our 21st century life but an amazing part of musical history. Thank you

Am more familiar with Skid Row and Sebastian Bach.
