Did you read all of the responses to Janice Young's original posting? #5611 listed several children. There was not a Merrill, however there was an Otto M who was 11 yrs old in 1910. Not the right age to have been born in 1892 but could you possibly have the wrong year? Also mentioned is the possibility that Arra is actually Anna. The lady who responded to Janice had several postings of censuses from early 1800's to 1930.
