Irwin asks:
I have learnt that the child of a mamzer is a mamzer. But is the child of a safek mamzer also a safek mamzer, or does it depend on whom he marries

The Kollel replies:
Irwin,
Marriage with a Mamzer always causes a Mamzer child, following the rule that a child becomes as Pagum (defected) as the Pagum parent- even when the marriage is permitted (Ger with Mamzer) (Kidushin 66b-67a)
So too, a Safek Mamzer (who cannot marry neither a Mamzer, Safek Mamzer, and regular Jew) passes his P'gam to offspring in all situations.
All the best,
