  Many authors have investigated the congruence relations amongst the
coefficients of power series expansions of modular forms $f$ in modular
functions $t$. In a recent paper, R. Osburn and B. Sahu examine several power
series expansions and prove that the coefficients exhibit congruence relations
similar to the congruences satisfied by the Ap\'ery numbers associated with the
irrationality of $\zeta(3)$. We show that many of the examples of Osburn and
Sahu are members of infinite families.
