There's a family tree on Ancestry that seems to match:

William Henry Yemm (parents James & Julia) married to Emily Partridge.

William died 16 Nov 1918 in Cuba, Fulton County, Illinois
Emily died Feb 1973 in Hot Springs National Park, Garland, Arkansas

4 children are recorded:

Alfred Henry Yemm 1903-1980
Catherine "Katie" Yemm 1905-1918
Alice Mabel Yemm 1907 -
Ellen "Nellie" E Yemm 1909 -

I have no other knowledge of this family other than the above derived from someone else's family tree so cannot vouch for its accuracy.

Wm Yemm, Emily plus infant on SS Luciana - departed Liverpool 12 Aug 1904 for New York.
