Here are the Munger burials that are found in the Greenwood Cemetery at Hayward. Note that some of these burial sites have no stones, so no further information could be provided as far as dates.
MUNGER (unknown) (no stone)
MUNGER Almira (no stone)
MUNGER Christine P 1882 1930
MUNGER Myrtle (no stone)
I see that there was a John M MUNGER born on 10 Dec 1892 in Sawyer Co. Since Albert and Allis did not marry until 1898, was this a child of Albert's brother? This is the only MUNGER birth listed in the pre-1907 birth index for Sawyer Co.
Other items found include:
The marriage of H D MUNGER to Rebeca MANTY on 06 Dec 1897 in the pre-1907 marriage index for Sawyer Co.
The marriage of Henry Egen MAU to Gortsude MUNGER on 30 May 1896, also in the pre-1907 marriage index for Sawyer Co.
In the 1910 Federal Census Heads of Household Index for Sawyer Co. are these MUNGER listings:
SURNAME GIVEN NAME AGE SEX RACE BIRTHPLACE LOCALITY PAGE SUBPAGE
MUNGER Anna L 52 F W Wisconsin Lenroot 266 A
MUNGER Burdette 48 M W Pennsylvania Lenroot 266 B
MUNGER Horace D 38 M W Iowa Lenroot 266 B
MUNGER Mabel 23 F W Wisconsin Hayward 240 B
Note that the above listed names might not necessarily be a head of household, but could simply be a name different from the actual household owner and is listed in this index because of the difference in names. I do not have the full 1910 Federal Census for Sawyer Co., but if you wanted to look the above info up, these families can be found on Microfilm Roll #T624-1717, part 2 on the pages and subpages listed above.
I found the above mentioned Ann(a) MUNGER in the northeast corner of Section 6 on the 1915 plat map located here - http://www.rootsweb.com/~wisawyer/platmaps/sc42n8w.htm
This is part of Lenroot Township. I then checked the partial listing of burials that I have for the Riverside Cemetery located at Seeley and found these MUNGER burials:
MUNGER, Anna Louise 1854 - 1931
MUNGER, Donald 1923 - 2000
MUNGER (?), Sanny Sjostrom 1903 - 1929
I'm sorry I can't answer your questions about Albert, but am hoping that this other MUNGER info will be helpful to you. Good luck with your research!
