My experience as a descendant of eastern European Jews is that if

I do not disagree, although have a known Ashkenazic third cousin, with a
common ancestor born ca. 1825, whose longest shared block with me is 9 cM.

She is an outlier, and her brother's longest shared block with me is 15
cM, but still, I think it's worth keeping in mind.
