Ida Smith Thompson(?) and family

Possible ID: Ida Smith (b. abt 1862, Fayette Co., TN) and family; husband may be a Mr. Thompson (Tomsen?); photo was probably made in the 1890's; photographer's stamp: Chickasha, Indian Territory. The present day town of Chickasha, OK, is in Grady Co., southwest of Oklahoma City. The photograph was saved by Ida's first cousin, Maggie Hall Smith, also of Fayette County, TN.

Who is this family? Is it Ida Smith from Tennessee? Who is her husband? Why did they move to Indian Territory? What happened to them?
