Oh my dear - you must be of my age, amd I'm so sorry to hear of your loss. I tried some hours ago to post my findings, but there were some difficulties with the server.
The line ketsele du mayns is the end of a chorus belonging to Di mame iz gegangen; I have it in Ruth Rubin; A Treasury of Jewish Folksong. - New York, N.Y. ; Schocken Books Inc. , 1950. - Pg. 54
Here The Mother brings a yingele (boy) home from the market to her daughter.
Two other versions in the internet change the gender; the mame brings a meydele home to her son: in
zemerl.com, with tune, and by the
Amsterdam Klezmer Band
Having read it again I just remember caressing my baby daughters and singing them song nearly a quarter of a century ago ... sweet memories.

With a compassionate hug
Wilfried
