Could you specify:
Do you mean Brookline Cemetery as in the city of Brookline, MA; or did you mean to say Brookdale Cemetery???
If you could be specific about what town you are talking about I might be able to find it in local listings...
I don't think there is a "Brookline Cemetery" in Brookline; but Walnut Hills Cemetery is found at the following:http://www.townofbrooklinemass.com/dpw/cemetery.htm
If you are looking for the city of Brookline, then I would try these folks.
