My grandfather was John Cottam, who married Elizabeth Welch. John died on 20th January 1917, aged around 28. I am looking for more information regarding John's ancestors. As far as I am aware, John and Elizabeth spent much or possibly all of their lives in Lancashire. Elizabeth died in 1962, aged 74, then living in Chorley, Lancs. Their children were Arthur and Alice; Alice being my mother. Any info much appreciated.
