Find Ancestors

Trying to find family of the following Johnsons. William Henry Johnson born March 1902 in the Fylde district Blackpool. His second marriage was to a Kathleen ? in about 1936/1938. They moved to Eastcote Middlesex about the same time. He had at least one brother known as Jack, may be John, who emigrated to Canada during the 1920s or 1930s. Believed to have been working for Canada Pacific Railway or some other railway company also believed to have been involved with a railway Union. He may have retired during the late 1940s or early 1950s as I vaguely remember seeing him around that time, when he visited the UK. Nothing else known about him. They had a sister known to my siblings as aunty Nellie, her madien name was Gosling. I would like to find the parents of William Henry, Jack/John and Nellie. More importantly is the daughter of William Henry Johnson and Kathleen Johnson, her name was was also Kathleen born in about 1938/1939, in Eastcote Middlesex She married Brian Lewis around 1959. They emigrated to the USA as Brian worked in either the aircraft or electrical industry and was transferred there by his employers. They had at least two sons, and visited us in about 1975 +/- a year or two. I think Brian and Kathleen may now be living in Gainsville Georgia 30506. Any information will be thankfully received etc. Ron G-T
