The marriage of Liselotte's parents soon turned into a disaster and domestic violent scenes were the order of the day. In 1657, Elector Charles I Louis separated from his wife Charlotte in order to marry morganatically with Marie Luise von Degenfeld, who thus became Liselotte's stepmother. Liselotte probably perceived her as an intruder, but was known that she loved at least some of her 13 half-siblings, the 'Raugrafen'. With two of her half-sisters, Louise (1661–1733) and Amalie Elisabeth, called "Amelise" (1663–1709), she kept a lifelong correspondence. Her half-brother Charles Louis (1658–1688), called "Karllutz", was a particular favorite of hers; she also called him "Black Head" ("Schwarzkopfel") because of his hair color and was ecstatic when he later visited her (1673) in Paris. His early death in battle deeply saddened her.
