On my family tree I have a Susannah Stratford who was born and died in Wiltshire yet the rest of her siblings are born in the USA. It says her parents are Joseph Stafford and Rebecca Arnold who were married in the USA. How can this be ?
Quite simply, the correct Susannah Stratford (LC37-NB3) has already been attached as a child of Joseph & Rebecca of Kent, Rhode Island. All you have to do in the first instance is to detach the Susannah Stratford of Wiltshire, England (GMYP-33V) from her relationship with this couple.
Ideally, you should go to the pencil icon alongside her name, click on "Remove or Replace" then go on to "Replace", by attaching her to her correct parents. However, I see there are no sources attached to GMYP-33V to indicate the exact details of her christening / birth, which would confirm who those parents actually were.
If you cannot discover (at this time) who they are, then click on "Remove" (instead of "Replace") to get her out of the wrong relationship with this American family. You can add her actual parents at a later date, hopefully.
If you have any problems with this procedure please come back and ask for further help. I would have done this myself, but thought it best not to directly involve myself without your go-ahead.
A further bit of "detective work" appears to show Susannah's parents were Edward Stratford and Ann Arman, who married at Purton, Wiltshire on 25 August 1745 - see https://www.freereg.org.uk/search_records/58187cdae93790eb7feb6a80/ann-arman-edward-stratford-marriage-wiltshire-purton-1745-08-25?locale=en.
Entering "Edward" as father in an FMP index search (for Cricklade parish) produced results for a number of children's baptisms - although adding "Ann" as mother removed them all! Perhaps she is not named in the baptism entries, or the name was recorded incorrectly.
Finally, I just found an Id for the Susanna(h) baptised in 1756, via the FIND function. It is M7NB-FZN. This shows her mother to be SUSANNA (not ANN), but I would still think it likely her father is the same individual who married at Purton (about 4 miles from Cricklade). There is one one other marriage of an Edward Stratford in Wiltshire for this period (1750 at Salisbury) and that does was to a MARY.
By the way, I don't know where you got your December 1740 Crickdale birth for her. I do not have a subscription for Find My Past, but the only possible match in the FMP index is for a Susanna Stratford baptised 1756 at Cricklade, Wiltshire.
The index has another Susan Stratford marriage, in 1762, at Cricklade - as well at the one for 1772 you have added. Although this could not be for the "1756 Susannah" (only 6 years after baptism) I think you need to take care with correct identification here. There are also 1762 and 1782 burials for a Susan(nah) Stratford at Cricklade.
Unfortunately, without a subscription, I cannot see the detailed facts about these entries - especially who "your" Susannah's parents were. Perhaps you (if you have access to FMP) or another member of this forum could check this for you. You could then add them at the same time you remove the (American) parents to whom she is currently attached.
Thanks Paul, you are wonderful. She (Susannah) married Henry Ockwell in 1772 so the 1756 birth/ baptism makes more sense for her. I'm still getting my head around it all.
