Reference for Kiddushin 3:13

רַבִּי טַרְפוֹן אוֹמֵר, יְכוֹלִין מַמְזֵרִים לִטַּהֵר. כֵּיצַד. מַמְזֵר שֶׁנָּשָׂא שִׁפְחָה, הַוָּלָד עֶבֶד. שִׁחְרְרוֹ, נִמְצָא הַבֵּן בֶּן חוֹרִין. רַבִּי אֱלִיעֶזֶר אוֹמֵר, הֲרֵי זֶה עֶבֶד מַמְזֵר:

R. Tarfon says: Mamzerim can cleanse themselves. How so? If a mamzer weds a bondswoman, the child is a bondsman. If he (his father) frees him, the son is a freed-man, (who may marry an Israelite). [Even ab initio a mamzer may marry a bondswoman to cleanse his children.] R. Eliezer says: He (the son) is a mamzer-bondsman. [the halachah is in accordance with R. Tarfon. And R. Tarfon concedes that if a bondsman marries a mamzereth, the child is a mamzer, for a bondsman has no pedigree.]
