May I give you a word of advice? If you want factually accurate
information, do not try to get it from internet sources. And trying to
get it by asking on newsgroups is even worse. Therefore I recommend you
get some reliable written sources.
I would suggest obtaining any or all of:

Jeremy Gaige's 4-volume set "Chess Tournament Crosstables," which
covers tournaments from 1851 through 1930.
"Chess Results, 1747-1900" and "Chess Results, 1901-1920" by Gino di
Felice. These contain both tournament and match data. The first
volume's match data is highly inaccurate, however.
"The Complete Book of Chess Tournament Crosstables -- Vol. 1
1851-1948" by Rick Melton. Deceptively titled -- this book is
"complete" like a rowboat is a battleship -- but it does have many of
the major events.
"Chess: The Records" by Ken Whyld. A wealth of chess statistics:
major tournaments and matches, Olympiad results, national
championships, etc.

If you have any ChessBase databases from the last few years, you
should be able to use the "crosstable" feature to get complete tables
for any events on the database. These may not be as accurate as, say,
Gaige's tables, but they're generally good. And it's one of the few
practical ways to get lots of tables for post-1930 events.
