This man memorialized in the next monument in St. Michael's Church, Linlithgow, Scotland, shouldn't be a mystery, or hard to find, and yet ....
I mean, it is inscribed with his name and date of death:
Each panel had its ancient crest
And motto done in Latin –
And ladies, old and young, were dressed
In costly silk or satin.
The confidence of one I gained
By regular approaches –
“These arms and mottoes,” she explained,
“Are purchased with the coaches.”
