Hi maddie,
hope you are well, i think you are right that the surname is probably Wilkes, and there is that Martha wilkes on the 1891 census as a teacher in Hampsted. Hopefully, bgoodman will receive the obituary very soon and it contains a new lead. I have been looking at the Elizabeth Winfield, she certainly seemed to have had a hard life, on the 1901 census she is back in the work house, now a widow with her daughter mary aged 13, henry aged 11 and another son, william aged 8. I dont know where her husband George was in 1891 and two of her sons john joseph and benjamin are not with her in 1901. If she was the Elizabeth Noah who married a George Winfield in 1886, she may have only known George Goodman for a short while because he died in 1888.
Look forward to hearing any further information
Bye for now
jackie
