My mother had said that his name was Charles Percy Lloyd. I could find no such person in the indexes, but one for a Peter Charles Lloyd. On my fathers birth certificate he was down as Charles Percy Lloyd, but on my parents marriage certificate as Charles Peter Lloyd and on my grandfathers marriage certificate as Charles Percy Lloyd, aged 21, although if the birth certificate is right he was only 19. No problem you say, check the census returns. In the 1881 census he is down as Peter C Lloyd, and in the 1891 census as just Charles Lloyd.
Dates match, addresses match, and ages agree as much as they ever do.
Are these people the same person, I hope so. Then came the Internet. A little dubious at first as to whether it would be of any help. Now that the LDS is online, perhaps the sky's the limit. I have in the past spent considerable time filtering through about 36,000 Lloyd names at the LDS history centre on the IGI computer with very little coming from it.
