Hi all, I am pleased to say that the person present at Mary's death was Sarah Goodman which would have been her mother Sarah Goodman (nee Hansted/anstee). They lived at Woodcock Hill, Rickmansworth. The cert didn't mention a house number. Mary died from TB, just like my great grand father George, her brother.
I am now awaiting a death cert for her brother John Goodman. He was baptized 1836 at Rickmansworth, another son of James Goodman (the blacksmith). He married in Middlesex to a Elizabeth/Betsy Lavender. I believe he died in 1909, registered Uxbridge. I was reluctant to order the cert at first as the age is not correct. However, with the Goodman family's past record of not knowing their true ages, it is a likely to be John.
