Frölich was born the daughter of colonel Hans Christoffer Frölich and Elisabet von Plessen.
She was married in Riga in Latvia, then a Swedish province, to Johann Henning Neumeijer, colonel in the Swedish army, whom she abandoned in 1684, when she arrived in Stockholm in Sweden in the company of the goldsmith Berendt Doerchmann and made herself known as a prophet and a preacher.
