Based on information primarily sourced from the Mathematics Genealogy Project and university records, here are the Ph.D. students in Mathematics who graduated from The Catholic University of America between 1910 and 1950 under the advisement of Professor Aubrey Edward Landry:

Thesis Title: Determination of Sets of Independent Conditions Characterizing Certain Special Cases of Symmetric Correspondences
19. Brother Cyprian John McNamara (1948)*
Thesis Title: The Reality of the Double Tangents of the Rational Bicircular Symmetric Quartic

Note, most of these are nuns. Other than Brother McNamara, Landry advised de Cleene (1927) who had received his Holy Orders 8 years earlier.

Landry had three male “civilian” students (Rice, 1917, Smith 1928, Eastham, 1931) and one female “civilian” student (Haynes, 1943). Rice was later hired full time at Catholic University. Eastham was soon hired to teach at Nazareth College. Haynes, 16 years later, was awarded the highest award the Pope (Pope John XXIII) could give to a woman: the Pro Ecclesia et Pontifice medal.

An asterisk next to a name means that I’ve obtain the PhD by inter-library loan (usually from CUA). If there are any additions or missing students, please let me know!
