A Celtic cross stands as a memorial to Saint Mother Theodore Guerin. Etched in the base are the words: "I sleep, but my heart watches over this house which I have built."

The Catholic Telegraph and Advocate in Cincinnati, Ohio, published the following notice about Saint Mother Theodore’s death. She died May 14, 1856.

“Died – At Saint Mary’s-of-the-Woods (sic), in the 58th year of her age, Wednesday, 14th inst., Sister St. Theodore, Superior General of the Sisters of Providence in Indiana.

“This woman, distinguished by her eminent virtues, governed the community of which she was the superior from its commencement, to the time of her death, a period of nearly sixteen years. Being a perfect religious herself, and endowed with mental qualities of a high order, she was peculiarly fitted to fill the duties which Providence assigned her.

“Not only her Sisters are bereaved by her death, but all those who knew her excellence and the amount of good she did, join in lamenting that she should have been removed from the sphere of her usefulness. To judge from the celestial expression of her countenance as she lay in death, there is every reason to believe that she has already taken her abode among the Saints in Heaven, enjoying the munificence of God, who rewards His servants ‘according to their works.’”
