Pierre, b...;m 13 janv. 1661[sic] à Jeanne Le Prevost, à Paris.
The 1661 date is assumed to be a typo and should be 1561. The entry for Pierre and Jeanne is placed between dates 1531 and 31 January 1561. It appears there are two typos - i.e. the marriage was either on 13 January or 31 January of 1561.
