Maurycy Mayzel, the last president of the Warsaw Jewish community before Holocaust, grandson of Dow Ber Meisels?

I have recently come to believe that my great great grandfather, Maurycy Mayzel, may have been the grandson of rabbi Dow Ber Meisels. Maurycy's father was Jakuba Mayzels, who I think is the son of Dow Ber Meisels.

R' DovBerish Meisels, A.B.D. Cracow and Warsaw This is a link to a profile that lists Jakob Wolf Meisels as one of Dow's sons, I believe that Jakuba Mayzels listed on my family tree may be the person who is listed in the attached profile.

I would love to hear any insight or knowledge that anyone has regarding this topic.
