I have just read an article on the English 1881 Census, in Your Family Tree magazine, May 2014. It mentions that when it was completed officials noted a rise in the number of 'deaf & dumb' people. It seems that many enumerators had recorded babies as being deaf & dumb because they couldn't talk!
Something to keep in mind not just for that census but any records. Look at the persons age before making judgements.
A Family Tree researcher for over 30 years and a blogger since 2010, I love to share what I find. This blog has opened up a new way to contact and keep in-touch with both family and friends. It mightn't always be genealogy related and you might not agree with my point of view but I want you to comment, ask questions and look upon this blog as 'friends having a chat'.
