Hi Linda,
Your best bet is to message the Profile Manager and collaborate with them on the profile. If they don't get back to you, as this is an open profile, you are welcome to contribute to it yourself. You can also always follow the Unresponsive Profile Manager process.
I notice you're wanting to use an Irish burial record and yet the profile currently says they died in the Netherlands. You'd probably need to show documentary evidence that they died in the Netherlands and were transported back to Ireland for burial, or that they actually died and were buried in Ireland.
In terms of how to cite burial record sources, there is no one way to do this, but I do something like this (made up example):
Burials (PR) England. York, Yorkshire. 28 March 1756. ANDREWS, Josiah. GS Film no: 62568. [URL familysearch] : accessed 12 April 2019.
which broken down is:
[Type of record] [Country] [Place, County]. [Date]. [Person's name] [GS Film no or equivalent reference] [link to source] [date accessed].
You might also be interested in joining a project to work with others on similar profiles. Here are some options:
Don't hesitate to ask if you have any other other questions. We're here to help in any way we can.
