I am by no means an expert, but I would say it is Cambria St .
First, off there are the wrong number of strokes for it to be Caroline. There is the obvious C and a, then the r and o. So far so good, but after the l, there is the i, n, an extra stroke and an e. (Assuming for the sake of illustration it says Caroline). That extra stroke doesn't make sense in there as part of the n or e. However, the strokes perfectly match Cambria.
Also, the character between the a and the tall letter (l / b) could not be an r and an o. The o doesn't come together on the bottom at all.
Comparing it to the surrounding handwriting also lends to the Cambria theory. Notice the similarities between the n in this entry and the n above in Highland Ave, Brother John, and Cleveland.
Of these reasons, the strongest is the first, but I think they all further prove that it says Cambria St Phila .
