Hello, I am looking for my great-grandfather William F Simms. I have very little information to go on.

I found him in the 1910 and 1920 census.

1920 census for Hamilton Co, OH:
SIMMS, William F. age 34 b. WV, both parents b. WV
wife Mabel age 34 b. IN, father b. PA, mother b. IN
dau Myrtle age 17 b. OH
son Royden age 7 b. OH
dau Dorcella age 5y11m b.OH
son Woodrow W. age 1y11m b. OH
father-in-law SMITH, Jackson A. age 63 b. PA, both parents b. PA
mother-in-law SMITH, Hattie age 63 b. IN, father b. PA, mother b. IN
brother-in-law SMITH, Claude D. age 25 b. OH, father b. PA, mother b. IN
sister-in-law SMITH, Marie age 24 b. OH, both parents b. OH
uncle SWALLOW, Frank P age 65 b. IN, father b. IN, mother b. PA

In 1910 in Cincinnati, Hamilton Co, OH:
SMITH, Jackson A. age 53
wife Harriet age 52
son Claude D. age 17
dau SIMMS, Anabel A. age 27
son-in-law SIMMS, William F. age 25
granddau SIMMS, Myrtle age 7
brother-in-law SWALLOWS, Frank B. age 55
PROCTOR, Joseph F. age 23
BROTHERS, William B. age 17
FRANZ, Harold E. age 22

In the 1930 census, the children are living with Hattie, but no sign of William or Mable/Anabel.

I cannot find him ANY where else. Can anyone offer help on where to go to find him? My family tree is dead here.
