For the Legendre–Stirling numbers of the second kind asymptotic formulae are derived in terms of a local central limit theorem. Thereby, supplements of the recently published asymptotic analysis of the Chebyshev–Stirling numbers are established. Moreover, we provide results on the asymptotic normality and unimodality for modified Legendre–Stirling numbers.
