I need a death date for Martha Dirkmaat Poorter of Broek op
Langendijk, Netherlands.  She was born there 28 Jan 1901.  I don't
think she ever left the Netherlands.  Her husband was Tieman Poorter. 
Thanks for your help.

january 15th, 1973.

then again, I can think of 1000s of other dates ;)

OK seriously then; I assume you are Dutch and in Holland, so here is
where to go to find out:
Afdeling Burgerzaken van de gemeente Langedijk is geopend op werkdagen
van 08.30 - 12.00 uur en op donderdagmiddag ook van 13.30 - 19.00 uur
(in juli en augustus tot 17.00 uur), en voor handelingen van de
burgelijke stand tot 17.00 uur.
Telefoon (0226) 33 44 25.

If you don't speak Dutch you could call them anyway: +31-226 334425.

Good luck!
