From his obituary it was apparent that he preserved his Quaker legacy.

Died at his residence in Flushing, on the 21st, Gilbert Lawrence, in the 95th year of his age. Precious indeed is the memory of our beloved friend, whose setting sun went down in brightness, after a long life of usefulness. He was a faithful elder in the meeting of which he had always been a member, and being clothed with a liberal spirit, he manifested that sweetness of disposition which endeared him to his friends. Long shall we miss his venerable form from its accustomed place in the house of worship, and listen in vain for the words of encouragement which frequently fell from his lips, giving evidence of his great concern for the welfare of society. His funeral took place from the meeting house on the 25th inst., where a very large concourse had assembled to pay the last tribute of respect to him who was worthy of double honor. Several testimonies were borne on the solemn occasion.

His residence, the Gilbert Lawrence House, survived at least until 1922.
