I've seen that some have the year of death as 1728 and others show 1729. I looked online and found a picture of the grave stone showing 1729.
The grave stone is a good source, but I'm also seeing Wikipedia cited as a source. Most genealogists agree that Wikipedia isn't a good source because anybody can post anything, right or wrong. But Wikipedia or any encyclopedia can be used as a reference to trace sources. If that source is found and verified, that ORIGINAL source should be cited, not Wikipedia.
