Mehetabel Blanchard and the Aeneid

Could the mystery gravestone in Malden be a footstone?

Footstones usually bear the deceased person's initials or name and, rarely, the year. Some footstones are a bit wordier.

Example:
Mehetable Blanchard, d. 1742, Malden, MA

According to the internet, that inscription is lines 606-610 of Book 1 the Aeneid.

In Latin:

In freta dum fluvii current, dum montibus umbrae
lustrabunt convexa, polus dum sidera pascet,
semper honos nomenque tuum laudesque manebunt,
quae me cumque vocant terrae.

In English:

While rivers run to ocean, while on the mountains shadows move over slopes, while heaven feeds the stars, ever shall your honour, your name, and your praises abide, whatever be the lands that summon me!

Joshua Blanchard, Mehetabel's husband, appears to have been a carpenter and, perhaps, a lover of Virgil.
