I ran across an obituary for J.R. Eychlesimer, born in New York. The spelling is slightly different, but it may be a misprint because of the unusual name. His age would put him born around the same time as Mary - could be a brother.
EYCHLESIMER- In this city, July 11, 1904, J.R. Eychlesimer, a native of New York, aged 72 years, 4 months and 29 days.
Friends and acquaintances qre respectfully invited to attend the funeral tommorrow at 4 pm from the Clark and Booth parlors. The remains will be taken to Oakland for cremation.
