Hi Marty -
D.Lansing LAMBERT died in Brooklyn.
On the www.germangenealogygroup.com
in the NYC Death Index:
Lansing LAMBERT 36y d.Sep 20,1870 Kings county
cert. # 7825
You can order his death cert. from the LDS for $4. From the Library Catalog on familysearch.org I found the microfilm information:
Title: Brooklyn death certs., 1862-1897
FHL Film # 1323684
To get the Request form, go to familysearch.org. On homepage, upper right, where it says "forms, maps,guides", click "forms". On new page scroll down to where it says "Requests for photocopies- census,books, microfilm...". This is form # 31768.
Download and print out form. Put the cert. # in the column all the way on the right, where it asks for registration #.
I suggest you send a moneyorder rather than a check, it'll go much faster that way. Copies are $2.00 ea., minimum order $4.00. You should get your copy in 15-23 days.
Because of Helen's post, I found him on the green-wood.com site for Greenwood cemetery -
LAMBERT, D.Lansing burial: 9-23-1870 Lot 3014 sec.70
I found something else, which I'll send in separate post.
