Your Almon appears with his parents in the 1860 Federal Census for the town of Lyndon in Sheboygan County.They are on page 503, dwelling 263, family 235

It looks like the family returned to NY for a time from this census.I show them on the index for the 1850 Federal census in Sheboygan and also on an 1855 census for WI in the town of Sheboygan.
There is a Jerome F. Brooks who served in the Civil War from Cascade, WI which is in the town of Lyndon.Chances are this is your Almon's father.

The pension record for Jerome F. Brooks shows that a pension was filed for him as an invalid on Feb. 26, 1869.In 1874, his wife Eliza J. files for his pension as his widow.This doesn't match with is wife's name on the 1860 census.I find no record of a marriage between Eliza and Jerome on the vital records index for Sheboygan County, so perhaps Hannah is a nickname for Eliza? I'm not sure of the middle initial for Hannah on the 1860 census, it could be a P or a J.Checking the 1850 census would probably clear this up, but those images aren't available to me now.
Searching the cemetery index, I don't find Jermome buried in any of the old cemeteries in Lyndon township, but the indexes only have tombstone transcriptions and not actual burials. If he doesn't have a tombstone, he wouldn't appear.Since his widow applied for the pension in 1874, perhaps he went to MO with his son?
