Dear Gerald, I wonder if the following will help. I looked up 1881 census and found John Bigrigg born Cockermouth and Mary Ann born Cornwall. You said their son William was born the same year. Free BMDs. Found a marriage in September Quarter 1880 in Cockermouth Registration District. The female names on the same page were Elizabeth Glaister and Martha Madron or Madrom. Looked at 1901 census index and found John Bigrigg straight away living in Cockermouth as a Mason Labourer. His age corresponded to that of 1881 census. I brought up all the Bigriggs living in Cockermouth and from the Page ID (obtained as I was told by hovering over the far left column next to the name and reading off the bottom task bar). I am not 100% sure how all this works but the same Page ID brought up Martha aged 44 born Cumberland, Egremont Jonathan 17 Margaret 7 George 4 Florence 2 Mary 2 mths Does this sound like your family or part of it? If you think so then no doubt you could check by downloading the page. Looked IGI baptisms for a Martha Madrom or Madron around 1857. Madrom is obviously a misspelling. Madron also brought up Maddern and all found by IGI were in Cornwall. Getting warmer. There was a Martha baptised 1854 at Sancreed daughter of James and Mary which was the closest. Back to 1881 census to see if a James or Mary, the parents, were in Cumberland but I could not find them. There were quite a few MADDIRN and MADDERN all born Cornwall in Cumberland at that time. One was a JAMES MADDON, born c. 1857 in St. Just (the St. Just near Lands End is about four miles from Sancreed) , Iron Miner boarding in Egremont. I wondered if he could be a brother? This might give you something to look into. My own feeling is that there is a mixture between the two lots of census information. The correct name should be Martha and her birthplace might either have been Cornwall as in 1881 census or Egremont as in 1901 census. The family may have come to Egremont when she was a small child for her father to work in the Iron Mines there. I hope this helps and please let us know how you get on with your search. Jill
