R' Aharon Karliner was the son-in-law of R' Mordechai Kreminitzer (the son of the Zlochever Maggid).

Once R' Mordechai Kreminitzer was sitting by a Melaveh Malka and was singing "Amar HaShem L'Ya'akov."

He was holding R' Aharon Karliner's daughter on his lap and said to her: I promise you that when you're engaged, your groom will be a king in Israel.

Later, the match was proposed with the son of the Rizhiner, R' Avraham Ya'akov (the first Sadigerer Rebbe). Although the Rhiziner was in the elder position and R' Aharon was still a young man, R' Aharon claimed that since the match was heavenly ordained because his father-in-law R' Mordechai Kreminitzer had promised that his daughter would become the Sadigerer Rebbe's bride, therefore he was exempt from paying a dowery. 

When it came to writing the wedding agreements, R' Mottele Chernobyler ruled that no honorifics be written because this could lead to one writing a more grandiose title than the other.

[marginal note re: R' Aharon was still a young man:] The Rizhiner was born in 1796 and R' Aharon in 1802?"
