From Moskovskoe Dvoryanstvo – Alfavitnyi Spisok Dvoryanskikh Rodov. (M: 1910) :
We have a "formulyarnyi spisok" entry for podpolkovnik Obukhov Ivan Trofimovich
From : http : //sr.rodovid.org/wk/ Посебно :ChartInventory/319195
We have podpolkovnik Obukhov Ivan Trofimovich identified as the commander of the Kaluzhskiy regiment, and his wife given as the former Olenina Yekaterina Dmitriyevna along with their children
So, we have two brothers, both staff officers, transferring into the Mogilevskiy regiment from the Revel'skiy regiment at the time of its formation. It look to me that the younger, Sergey Trofimovich, had left this world by April 1809 and that the elder, Ivan Trofimovich, survived the Swedish War winning the Saint-Vladimir 4th class and going on to command the Kaluzhskiy regiment, and to retire in November 1811.
I have not found direct information on which of the two commanded and was heavily wounded at Pulkkila in early May 1808. As the commander was identified as a "colonel", maybe it was Ivan Trofimovich.
