Nope, not an ancestor of LCR, though there are Roseberry's in the tree. Recorded all the scoop in case the lines cross someday. I took individual photos of the bricks, and as I began to transcribe them for you, I realized that the name Roseberry on each brick signified the town of Roseberry and the family living there, and not that they were Roseberry's!! For example:
Alfred & Carrie
So none of the bricks appear to be actual Roseberry family members, but rather folks that lived in Roseberry! Interesting now that I've caught that!
