Just saying it could be the right Ivy but not necessarily, until I can find some admission records.
I recalled thinking the obit for John M Brown packed a lot more in that was possible, so have just checked. Not so many mismatches as I recall when I was trying to write up his timeline. Possibly some things are not in chronological order. His obit was mostly drawn from his bio in the 1901 'South Bend and the Men Who Have Made It' that says:
He was born in Liverpool July 17 1859
Father David E Brown handled real estate of the Corporation of Liverpool and a highly prominent official.
Educated at private schools in his native city and Crosby Grammar School for Boys.
Then engaged in agricultural pursuits in southern England
In 1877, came direct to South Bend
Clem Studebacker farm 2 yrs (so to 1879)
Then for a time at Singer Mfg Co (1879-?)
Then engaged in farming for Thomas D Summers (but 1885 has John M Brown in South Bend city directory as resident in South Bend, a clerk, county auditor's office)
Returned to South Bend and worked for Hon Marvin Campbell as hardware store clerk then bookkeeper 3 yrs
Tendered a clerkship by county auditor Aaron Jones and accepted it as deputy county auditor to 1891 (when Jones term expired)
When county auditor Robert Myler elected, he continued as deputy for one year.
Resigned to be Assistant Cashier South Bend National Bank until 1897
Made deputy county auditor by George W Loughman, where remained until 1899 [need to check this date with the original]
1898 elected to county auditor - term expired 1903
Other records:
1877, June - John Brown steerage, 18, labourer, Liverpool to NY passage.
1885 - clerk in county auditor office (directory)
1900 - county auditor (census and newspaper article)
1903 - after auditor term ended went to Toledo for a few months, then to Buffalo (obit)
1910 - book keeper for Machine Co (census; also stated arrived 1875) - was that Singer Machine Co?
Gretna Green analogy was it was the nearest place over the border to get married
