Nope, never saw that. Do you know around what minute it appeared? Someone might be able to screencap it.
The plot is shared by the two sisters -- Lavina and Delilah -- and their father, Ovid. No Michael there. I spent some time searching for records for a Lavina Constant the other night and came up empty.
There are a few Constants among the 25,000 or so burials at Riverside Cemetery, but no Michael that I've located.

It didn't give her name as Shaw-Constant. The "L.O." on the first screencap probably stands for "Lot of," so "Lot of Shaw and Constant families." I know for a fact that my father's family cemetery writes it out that way, so it wouldn't surprise me if other cemeteries abbreviate the same way. It can't be initials for Lavina; she had no "O" name anywhere in the mix.
