Hi Maggie
THere is a distant connection to my family thru Doris's 2nd husband. Since my direct descendents left the IOM in 1810 i have focused my research from 1600-1900. I probably have no direct family left on Mann, but did find a disant cousin who I work with along with Sue. we are researching the early Radcliffe families from Andreas of which there are about 5 or 6 branches. Sorry I can't help you with the post 1900 families.
