Correspondence between Einstein and Marić, discovered and published in 1987, revealed that in early 1902, while Marić was visiting her parents in [[Novi Sad]], she gave birth to a daughter, [[Lieserl Einstein|Lieserl]]. When Marić returned to Switzerland it was without the child, whose fate is uncertain. A letter of Einstein's that he wrote in September 1903 suggests that the girl was either given up for adoption or died of [[scarlet fever]] in infancy.<ref name="HBMes"/>{{sfnp|Calaprice|Lipscombe|2005|pp=22–23}}

Einstein and Marić married in January 1903. In May 1904, their son [[Hans Albert Einstein|Hans Albert]] was born in [[Bern]], Switzerland. Their son [[Einstein family#Eduard "Tete" Einstein (Albert's second son)|Eduard]] was born in Zurich in July 1910. In letters that Einstein wrote to Marie Winteler in the months before Eduard's arrival, he described his love for his wife as "misguided" and mourned the "missed life" that he imagined he would have enjoyed if he had married Winteler instead: "I think of you in heartfelt love every spare minute and am so unhappy as only a man can be."<ref name="MlQLY"/>

Following an episode of acute mental illness at about the age of twenty, Einstein's son Eduard was diagnosed with [[schizophrenia]].<ref name="Robinson2015a"/> He spent the remainder of his life either in the care of his mother or in temporary confinement in an asylum. After her death, he was committed permanently to [[Burghölzli]], the Psychiatric University Hospital in Zurich.{{sfnp|Neffe|2007|p=[https://archive.org/details/einsteinbiograph00neff/page/203 203]}}
