The only artist that fits both the spelling and the dating of 1883 is Alois Harner, also known as Aloys Harner, a last half of the 19thC Austrian.
Your oil painting, as described with no picture, would have an estimated retail value of $500-900 as a decorative piece. This value assumes good condition and depends on sale geographic location.
As for where to sell close to retail, I suggest these sites where you have the widest pool of buyers -
Accept PayPal only.
Etsy.com - small fees - 20 cents to list plus 3.5% final price.
In general, a private seller to a dealer, via consignment or at auction can expect 30-50% of estimated retail value.
Insurance replacement values are usually about 10% more than retail values.
