Presume John would have been in Ireland and maybe married there before coming to England.
The 1911 should state how many years married to narrow it down.
Back to Ellen there was a marriage in Strood - 1889 I think - but I discounted it as it linked to a Helen Dyke who was in Ireland in 1901 and single and a death as Ellen F Dyke in Middlesex.
Maybe it needs a second look. Groom was Edward Dyke - no children.
Blimey. I completely forgot about this reply. I saw the hint later on Ancesrtry (the only site to have it) and wow! Two birds with one stone. This is indeed Ellen Lyons - mystery solved. And Jane, her next youngest sister married Edward's brother Elias, with a life in the North Woolwich area on the boats. The details fit and have no qualms.
So what am I left with? In order, what happened Catherine Lyons, Harriet's twin? What happened to Harriet herself, my great-grandmother. She had another son William to whom I have a birth certificate for (July 29 1912, 10 Trafalgar Road, Gravesend, Kent). She later appears as a witness at Johanna's wedding (the elusive "Annie") in 1910. Did William ever marry? No visible records. And John Lyons Sr and Mary Lyons Sr - any details for either. I believe Mary (full name Mary Ann as per children's baptismal records (they lived next to St George's Church but attended St John the Evangelist Church) was the daughter of a William Davis, born approx 1816 in Broseley in Shropshire and later married to a Sarah Gates in Uxbridge/West Drayton, however, I also believe Sarah to be a stepmother). Bearing in mind the numerous descendants, from 10 children, I would hope there may be more interest from distant relatives
Though I have served further for Mary Lyons's death, bear in mind that with the numerous years of birth/ages, it could well be the same lady.
I still have no idea with the various dates as to where John Lyons Sr came from, exactly. Any other ideas? Birth Certificates and/or Marriage Certificates for all ten children available if necessary...
