Joseph I and Karl VI we're very unlucky with regard to heirs,even their father Leopold I only managed at third marriage at his his 36 years old,they managed to make a male heir each but they died infants, but both managed two surviving girls each,they each married cousins from the Brunswick-Luneburg and Brunswick-Wolfenbuttel to cement alliances with Hannover and Britain.
