According to https://en.wikipedia.org/wiki/Willem_Teellinck his wife was Martha Greendon not Gregson.
https://www.vondel.humanities.uva.nl/ecartico/persons/48089 names his wife as Martha Grujns alias Martha Angelica Greenston.
https://www.dbnl.org/tekst/molh003nieu05_01/molh003nieu05_01_1130.php mentions a marriage in 1604 on 26 September at Zierikzee
I would like to verify that she is the same person as Martha Gregson.
