Recently Avrami Groll told us that all JewishGen Discussion Group and SIG group messages have been archives in this new system. I went to https://groups.jewishgen.org/g/main/topics and searched for "recte." The "r" in your surname stands for recte. f stand for false. v stands for vel. You can also search for "false" and "vel." This has been discussed over the years relating to Galician record.
