Rabbi Avraham II ben Moshe I Heller-Wallerstein Fränkel, Maharal son in Law of #4 - Abraham ben Moshe Heller Wallerstein

I have combined the two Abraham ben Moshe's as we try to sort things out.

According to the Frankfurt Memorbuch 122, 8, the husband of Bela Heller Wallerstein who dies in Vienna is Abraham ben Moshe Levi Heller. See https://media.geni.com/p13/db/6e/9c/2e/534448502124b295/screen_shot_2019-11-16_at_10_original.jpg.?hash=b16fd2bb71458924f0e94d1334445acde0ddc7a613b695daf5e5bc1a0cb99a5a.1713337199 Wachstein identifies him as Abraham ben Moshe Heller-Wallerstein who dies in Vienna.

Wachstein, who is very reliable, corrects his earlier mistake on the date of death (so not 1572) and thinks Abraham must have died 1610-1613. See https://media.geni.com/p13/b7/86/34/ea/5344485021be4659/screen_shot_2019-11-16_at_12_original.jpg?hash=c3f56a7fbfcb9d0a8e79ae0e6e16b60181e496521b1c839ade317b1d3744c956.1713337199

Rachel Heller-Wallerstein, [Maharal dau. #6] dies in 1632 in Prague as the widow of Rabbi Abraham Wallerstein.

I need confirmation that the Maharal's daughter Reichel's husband Abraham is in fact the son of Moshe Wallerstein. Can anyone find a real source (not just some genealogy that someone else has pieced together)? Basically every genealogy says he is Abraham ben Moshe, but I don't yet see a good source for that.
