I'm looking for obits, death records or cemetery location for Elias Platte Jenison and wife Martha(Summers) Jenison. Martha died sometime between 1900-1910 and Elias died after 1920. After Martha's death the family was split up. Elias was born in 1855 and Martha was born in 1869 in Iowa. They were married in 1889 in Sioux county and had three children, Myrtle born 1890, Estella born 1892 and Merle born 1900. If there are any birth records on the children I would love that info. If anyone has any suggestions on where to look for this info i.e. newspapers, cemeteries, city directories etc. I would appreciate it.
