This was printed on bookplates my dad had purchased from the Antioch Bookplate Company when I was a small child, but they had wrongly attributed the poem to Richard Lovelace. Because these aren't the opening lines, and most poetry was only indexed by first lines, I spent many hours in a fruitless search for the source. Thank you, Internet!
Ah, yet, ere I descend to the grave
May I a small house and large garden have;
And a few friends, and many books, both true,
Both wise, and both delightful too!
