The book Some of the Descendants of Peter Cleaver by William Jessup Cleaver says that Rebecca Cleaver married Peter Bodine. No children are listed for them in the small tree. Later it says she died before 1837 and "left three small children at her early death." The book says the name of her mother is not certain.
My guess is that the unknown male's name was Peter Bodine since no other child in this family has that name and it was important in the family. They seemed to follow Dutch-like naming customs. See my Notes on Sabillah for more on her.
James Dallas Bodine's biography says that he was the youngest of ten children. Taking that into account, here is some census info:
From Pennsylvania Federal Census Records:
1830 Catawissa Twp., Columbia Co.: Peter BODINE males 2(0-4), 1(5-9), 1(30-39); females 2(5-9), 2(20-29).
Looking at the census info above, it looks like there is one male we don't know about (the one who was 5-9 years old) and one female we don't know about (one of the 2 who was 5-9). The two males 0-4 were David and Charles. The other female 5-9 was Elizabeth.
My guess is that this male died soon after 1830 and the female (probably Sabillah) was over 13 years of age by 1833 when Peter said he only had four minor children: Elizabeth, David, Charles, and Brittain (minors were under 14). This scenario would give us ten children in this family.
