Hi, Barbara. Thanks for pointing out the problems with that profile. But please know that you are not writing to "WikiTree Management." That page was created by an individual who volunteered to contribute to WikiTree. If you are interested in helping to improve and expand our "tree," you also could volunteer.
Now I'll climb off that soapbox and address your question. ;-) Thanks for providing that reference to the Kingston church records. It's clear from that record that Hellegond was the mother, so I've corrected her gender. From the profile and its edit history, it looks to me like everyone who edited it thought her name was van Boerum, so it's not obvious where ":Van Buren" came from! Before we change a person's Last Name at Birth (LNAB) at WikiTree, we need to make sure we've found the best estimate of the person's LNAB, and we need to see whether there are other profiles for this person that should be combined with this one.
That 1679 baptism record shows her last name as the patronymic Willems, not van Boerum. If in 1679 she wasn't using the family name van Boerum, chances are good that her LNAB was Willems.
I'lll start looking for other records from her life. If you know of other sources -- particularly for her name, please post them here. Or (even better) how about joining us here?
