Dirk (b 1814) was adopted by his uncle (Ubbo, b abt 1788) and received the same surname as his uncle. Dirk's mother, prob Antje, had him out of wedlock and when she died (an unmarried woman), her brother (Ubbo, b. abt 1788) adopted the little boy and gave him the Beving family Surname (the same name as Dirk's natural mother, Antje and his adopted uncle, Ubbo). The explanation comes from Trientje (who married Spekker). She told the story to her great-granddaughter Anni Kromminga (who married Johan Peter Skekker) and Anni told the story to her grand-daughter Almuth who lives in Munich (year 2003). Trientje was the sister of Antje and Ubbo (b. abt 1788), so she was little Dirk's (b 1814) aunt. Dirk's father is referred to as "Uncle Everts Beving" who adopted little dirk. Uncle Beving's name was Ubbo Everts Beving - and little Dirk was given the family surname.
