What you show in parentheses is not a standard genealogical type of abbreviation, but could represent the compiler's own abbreviation format.
Some written genealogical accounts begin a summary regarding a particular individual by giving a series of ancestors this way:
"John SoAndSo (RICHARD4, DANIEL3, JOHN2, JOHN1) . . ." with the names in parentheses being in order the first names of father, grandfather, etc. with their generation numbers as in the overall account.
Much older genealogical accounts might represent a similar series of ancestors like this:
-- with the numbers representing the child number of, first, the subject of the paragraph, next the child number of the child's parent, then the child number of the child's grandparent. The person reading the account would have to try to follow the numbers back in the right order in the account that they had a copy of.
It is possible that the writer of what you have represented preceding generations using the capitalized letters, in order going back in time.
