I realized I forgot to look for Mary Wulff in 1900 to find the husband -
1900 CREIGHTON, KNOX , NE WOLF Henry, age 34, farmer, born March 1866 Germany both parents born Germany, married 2 years
A. Mary, age 23, wife, born Jan. 1876 IL both parents born Germany, married 2 years, 1 child born, 1living
George W., age 1, son, born March 1898 NE father born Germany mother born WI (odd as she was born IL, but census are often mixed up)
BUNGE Emma, age 12,sister-in-law, at school, born Feb. 1888 NE bothparents born Germany
There is a tree on ancestry that shows Henry Wulff(son of Henry and Mary) and wifeDorothy Dalzell but no marriage year for them and does not show any other marriages for him - but then they show right death for Dorothy but do not show that she was a Patterson at the time.
It still looks to me like he is very likely the right Henry.
