Something like this, maybe?
"""
This iterates through a file, with subloops to handle the
special cases. I'm assuming that Jimmy and Sarah are not the
only people of interest. I'm also assuming (for no very good
reason) that you do want the separator lines, but do not want
the "Person:" lines in the output file. It is easy enough to
adjust those assumptions to taste.
Each "Person:" line will cause a file to be opened (if it is
not already open, and will write the subsequent lines to it
until the separator is found. Be aware that all files remain
open unitl the loop at the end closes them all.

f = open('shouldBeDatabase.txt')
for line in f:
if line.find('Person:') >= 0:
ofkey = line[line.find('Person:')+7:].strip()
if not ofkey in outfs:
outfs[ofkey] = open('%s.txt' % ofkey, 'w')
outf = outfs[ofkey]
while line.find('-----------------------------') < 0:
line = f.next()
outf.write('%s' % line)
