I "assumed" the spelling of the last name might have been mispelled...after all it was in an obituary. So back to the main source:
The full obtuary:
The Sheboygan Press, Sheboygan, WI, Nov 24, 1951.

The body will lie in state at the funeral home after 7 p.m., today, until the hour of services on Monday.
At 8 p.m., today, and Sunday the rosary will be prayed at the funeral home.
Now, the obituary indicated Mary Sigman was the sister of John, not daughter.That helps identify her age.It also identified other siblings, to include Charles:
