Data from Wachstein:
The father of Ahron
R' Aaron Moses Ezekiel Lwow, 1st Rabbi of Treves and then A.B.D. of Westhofen
is Moses Lemberg (Lewow Lemberg nach dem Wohnsitze des Urahnen Moses, der in Lemberg gewirkt hat)
Rabbi Moshe of Lemberg Lwow Lemberger
But there is no data on Moses Lemberger-Lewow Parents, or wife.
In Eger family tree:
Ahron is the son of Rabbi Moshe Levov from Lemberg and of Keila Katz.
There is no data there of Moses’s parents, but of his wife.
She was the daughter of Moses Katz from Luzk- Wolhynia) (no data on his parents either) and of Nissla Katzenellenbogen , the daughter of Meir Katzenellenbogen 1565-1631 chief rabbi Brisk and of Hinda Horowitz. – this is how it appears in the Hebrew family tree.
In the English:
Kaila Katz (wife of Moses Levov) is the daughter of Moshe Katz and here his wife name is Gisela, the daughter of Meir Katzenellenbogen.
So I guess Nisla and Gisela are the same. And what is now NN Cohen Katz is Keila and her fathe ris Moses Cohen who appears at the moment as Moses’ Lewow father.
