Robert Friedrich Grunert was born May 26, 1860 in Saxony, Germany to Carl Frederick and Augusta Bertha Grunert (nee Werner). Robert came to the US with his family May 27, 1873 aboard the ship 'City of Limerick', which landed in New York. The family was living in Milwaukee by at least 1876, when his sister Lizzie was born. On June 1, 1880 he married Pauline Brandau in the town of Lake (Bay View) which is just South of Milwaukee, and they had at least 12 children, all born in Milwaukee, WI:

Heinrich stillborn 7/26/1881
Anna born 9/26/1884 (died 1884 Milwaukee)

I believe his wife died around 1926. Pauline is listed on a Milwaukee directory for 1926, but not for 1927. She is not listed in her son's obituary in 1929. Here are his Milwaukee directory listings during that time:

1926 - 1389 9th (Pauline listed)
1927 - 1389 9th
1928 - 1313 W. Garfield (his son is living here on the 1930 census)
1929 - 1313 W. Garfield
1930 - No listing in the Milw Directory, but his son is living at 1313 W. Garfield
1931 - No Grunerts at 1313 W. Garfield, 2617A does not exist yet.
1932 - 2617A N 35th (listed as Widower)

Robert was a carpenter by trade. and became a US citizen on May 17, 1921. He died Nov 17, 1938.

Evergreen Cemetery is now called Glen Oaks Cemetery.
