DO You Know a FULBRIGHT from the Past? SEARCHING For Brayden Fulbright of Ireland.

I am searching for a Brayden Fulbright whose roots may have started in Germany or England, then gone to Ireland, then the US. He may have been born about 1811, but not sure where, He lived in Ireland, around County Cork, in 1830 to 1840, family lore tells us. Arrived in America sometime between 1850 and 1860. Settled in at Detroit, Michigan, then moved on to Iowa. Married a Delphine Sanderston in 1842 in either Michigan or elsewhere. Had a g g grandfather of mine, Maynard Fulbright, and that’s all we know. I have the line down from Maynard, just would like to know more about Brayden and his relations and ancestors. Thanks if anyone knows anything or has a helpful idea for me to pursue. Jason Fulbright
