Hello.
I am looking for any information on William Henry Shackleton. Born around 1863 in England. Emmigrated to the U.S. in 1889 and was naturalized in 1926. He lived in New York. He has at least two siblings: Flora and Emily. He was married to Margaret Clarke, who died before 1902, and had 3 children: Louise, Beatrice, and Florence. He also married Martha Ramsay/Ramsey and had 4 children: George, Sarah, William, and Lillian. He may also have married Anne Walmsley at some point and had Louisa, but I cannot make that connection very clearly.

So my search has hit a brick wall with WILLIAM HENRY Shackleton. I cannot find a definete birth information for him or his siters and I certainly cannot find any information on his parents whatsoever.

Any help is greatly appreciated!
Thank you!!
