Seeking information

I'm now trying to trace a Hannah McAdam and her brother John Wright McAdam who, I suspect, emigrated to the States with their mother Margaret Ashbridge Wright McAdam after their father Thomas McAdam died.

I also have additional information on McAdams in Whitehaven - all baptised in Holy Trinity, as well as McAdams of Carlisle.
Am looking forward to hearing from anyone

Thomas McAdam married Margaret Ashbridge Wright 6 Dec. 1845 at St. Mary in Carlisle. Their son, John Wright McAdam b. 31 Oct. 1870 in Whitehaven.
